2 Matter and Energy Matter anything that occupies space and has mass (weight) Energy the ability to do work Chemical Electrical Mechanical Radiant Slide 2.1

3 Composition of Matter Elements Fundamental units of matter 96% of the body is made from four elements Carbon (C) Oxygen (O) Hydrogen (H) Nitrogen (N) Atoms Building blocks of elements Slide 2.2

4 Atomic Structure Nucleus Protons (p + ) Neutrons (n 0 ) Outside of nucleus Electrons (e - ) Figure 2.1 Slide 2.3

5 Identifying Elements Atomic number Equal to the number of protons that the atoms contain Atomic mass number Sum of the protons and neutrons Slide 2.4

6 Atomic Weight and Isotopes Isotopes Have the same number of protons Vary in number of neutrons Atomic weight Close to mass number of most abundant isotope Atomic weight reflects natural isotope variation Slide 2.5

7 Radioactivity Radioisotope Heavy isotope Tends to be unstable Decomposes to more stable isotope Radioactivity Process of spontaneous atomic decay Slide 2.6

8 Molecules and Compounds Molecule two or more like atoms combined chemically Compound two or more different atoms combined chemically Slide 2.7

9 Chemical Reactions Atoms are united by chemical bonds Atoms dissociate from other atoms when chemical bonds are broken Slide 2.8

10 Electrons and Bonding Electrons occupy energy levels called electron shells Electrons closest to the nucleus are most strongly attracted Each shell has distinct properties Number of electrons has an upper limit Shells closest to nucleus fill first Slide 2.9

11 Electrons and Bonding Bonding involves interactions between electrons in the outer shell (valence shell) Full valence shells do not form bonds Slide 2.10

12 Inert Elements Have complete valence shells and are stable Rule of 8s Shell 1 has 2 electrons Shell 2 has 10 electrons 10 = Shell 3 has 18 electrons 18 = Figure 2.4a Slide 2.11

13 Reactive Elements Valence shells are not full and are unstable Tend to gain, lose, or share electrons Allows for bond formation, which produces stable valence Figure 2.4b Slide 2.12

14 Chemical Bonds Ionic Bonds Form when electrons are completely transferred from one atom to another Ions Charged particles Anions are negative Cations are positive Either donate or accept electrons Slide 2.13

15 Chemical Bonds Covalent Bonds Atoms become stable through shared electrons Single covalent bonds share one electron Double covalent bonds share two electrons Figure 2.6c Slide 2.14

16 Examples of Covalent Bonds Figure 2.6a, b Slide 2.15

17 Polarity Covalent bonded molecules Some are non-polar Electrically neutral as a molecule Some are polar Have a positive and negative side Figure 2.7 Slide 2.16

18 Chemical Bonds Hydrogen bonds Weak chemical bonds Hydrogen is attracted to negative portion of polar molecule Provides attraction between molecules Slide 2.17

19 Patterns of Chemical Reactions Synthesis reaction (A+B AB) Atoms or molecules combine Energy is absorbed for bond formation Decomposition reaction (AB A+B) Molecule is broken down Chemical energy is released Slide 2.18

20 Synthesis and Decomposition Reactions Figure 2.9a, b Slide 2.19

56 Title: Cellular Transport Essential Question: How does the selective permeability of the plasma membrane allow substances to move into and out of the cell?

57 Essentials of Human Anatomy & Physiology Elaine N. Marieb Seventh Edition Chapter 3 Cells Slides Lecture Slides in PowerPoint by Jerry L. Cook

58

59 Cellular Physiology: Membrane Transport Membrane Transport movement of substance into and out of the cell Slide 3.20

60 Cellular Physiology: Membrane Transport Passive transport Molecules move due to Kinetic Energy, but no energy is added to the system Slide 3.20

61 Passive Transport Processes Diffusion Particles tend to distribute themselves evenly within a solution Movement is from high concentration to low concentration, or down a concentration gradient Figure 3.8 Slide 3.23

62 Passive Transport Processes Types of diffusion Simple diffusion Unassisted process Factors Affecting Diffusion Solutes are lipid-soluble materials or small enough to pass through membrane pores Size of molecules and temperature determines the rate Slide 3.24a

63 Passive Transport Processes Facilitated diffusion Allows lipid insoluble substances (i.e. glucose) to pass through using a protein carrier Facilitated Diffusion Animation

64 Diffusion through the Plasma Membrane Figure 3.9 Slide 3.25

65 Passive Transport Processes Types of diffusion Osmosis simple diffusion of water Highly polar water easily crosses the plasma membrane Osmosis & Diffusion Animation Slide 3.24b

66 Passive Transport Processes Hypotonic Solutions: contain a low concentration of solute relative to another solution (e.g. the cell's cytoplasm). water diffuses into the cell, causing the cell to swell and possibly explode. Slide 3.24b

67 Passive Transport Processes Hypertonic Solutions: contain a high concentration of solute relative to another solution (e.g. the cell's cytoplasm). water diffuses out of the cell, causing the cell to shrivel. Slide 3.24b

68 Passive Transport Processes Isotonic Solutions: contain the same concentration of solute as an another solution (e.g. the cell's cytoplasm). water diffuses into and out of the cell at the same rate. Animation Slide 3.24b

69 Tonicity Examples!!

70 Example #1 Cell membrane is not permeable to NaCl. Cell with 0.9% NaCl Solution is 3% NaCl Show -What will happen to the cell? -Where will most of the NaCl solutes be? What direction will it move? -Where will most of the water molecules be? What direction will it move? -Is the solution hypertonic? Hypotonic? Isotonic?

71 Example #1 Cell membrane is not permeable to NaCl. Cell with 0.9% NaCl 0.9% NaCl 99.1 % Water Solution is 3% NaCl 3% NaCl 97% Water

72 Solution is Hypertonic -Water leaves the cell -NaCl does not move -Cell shrinks H 2 O S H 2 O H 2 O H 2 O S S S Hypertonic Solutions: contain a high concentration of solute relative to another solution (e.g. the cell's cytoplasm). When a cell is placed in a hypertonic solution, the water diffuses out of the cell, causing the cell to shrivel.

73 Hypertonic Example If red cells are placed in sea water (about 3% salt), they lose water by osmosis and the cells shrivel up. Sea water is hypertonic to their cytosol. Similarly, if a plant tissue is placed in sea water, the cell contents shrink away from the rigid cell wall. This is called plasmolysis.

74 Hypertonic Example Sea water is also hypertonic to the ECF of most marine vertebrates. To avoid fatal dehydration, these animals (e.g., bony fishes like the cod) must continuously drink sea water and then desalt it by pumping ions out of their gills by active transport.

75 Hypertonic Example Marine birds, which may pass long periods of time away from fresh water, and sea turtles use a similar device. They, too, drink salt water to take care of their water needs and use metabolic energy to desalt it. In the herring gull, shown here, the salt is extracted by two glands in the head and released (in a very concentrated solution it is saltier than the blood) to the outside through the nostrils. Marine snakes use a similar desalting mechanism.

76 Example #2 Cell membrane is permeable to NaCl. Cell with 60% NaCl Solution is 10% NaCl Show -What will happen to the cell? -Where will most of the NaCl solutes be? What direction will it move? -Where will most of the water molecules be? What direction will it move? -Is the solution hypertonic? Hypotonic? Isotonic?

77 Example #2 Cell membrane is permeable to NaCl. Cell with 60% NaCl 60% NaCl 40% Water Solution is 10% NaCl 10% NaCl 90% Water

78 Solution is Hypotonic -Water moves into the cell -NaCl moves out of the cell -Cell swells Hypotonic Solutions: H 2 O S H 2 O H 2 O S S H 2 O contain a low concentration of solute relative to another solution (e.g. the cell's cytoplasm). When a cell is placed in a hypotonic solution, the water diffuses into the cell, causing the cell to swell and possibly explode. S

79 Hypotonic Example A red blood cell placed in a hypotonic solution (e.g., pure water) bursts immediately ("hemolysis") from the influx of water. Plant cells and bacterial cells avoid bursting in hypotonic surroundings by their strong cell walls. These allow the buildup of turgor within the cell. When the turgor pressure equals the osmotic pressure, osmosis ceases.

80 Example #3 Cell membrane is permeable to NaCl. Cell with 0.9% NaCl Solution is 0.9% NaCl Show -What will happen to the cell? -Where will most of the NaCl solutes be? What direction will it move? -Where will most of the water molecules be? What direction will it move? -Is the solution hypertonic? Hypotonic? Isotonic?

81 Solution is Isotonic -Water moves into and out of the cell equally -NaCl moves into and out of the cell equally -Cell stays the same H 2 O H 2 O S H 2 O H 2 O S S S Isotonic Solutions: contain the same concentration of solute as an another solution (e.g. the cell's cytoplasm). When a cell is placed in an isotonic solution, the water diffuses into and out of the cell at the same rate. The fluid that surrounds the body cells is isotonic.

82 Osmosis is important! A report in the 23 April 1998 issue of The New England Journal of Medicine tells of the life-threatening complications that can be caused by an ignorance of osmosis. Large volumes of a solution of 5% human albumin are injected into people undergoing a procedure called plasmapheresis. The albumin is dissolved in physiological saline (0.9% NaCl) and is therefore isotonic to human plasma (the large protein molecules of albumin have only a small osmotic effect). If 5% solutions are unavailable, pharmacists may substitute a proper dilution of a 25% albumin solution. Mixing 1 part of the 25% solution with 4 parts of diluent results in the correct 5% solution of albumin. BUT, in several cases, the diluent used was sterile water, not physiological saline. SO, the resulting solution was strongly hypotonic to human plasma. The Result: massive, life-threatening hemolysis in the patients. Source:

83 It s your turn!! You and your partner write an example where the solution is either hypertonic or hypotonic. Give the example to the partners across from you, and vice versa Solve the problem! Be ready to share out!

84 Title: Cellular Transport Essential Question: Describe how various transport processes account for the directional movements of specific substances across the plasma membrane.

85 Cellular Physiology: Membrane Transport Active transport The cell must provide metabolic energy Slide 3.20

86 Active Transport Processes Transport substances that are unable to pass by diffusion They may be too large They are not lipid soluble. They may have to move against a concentration gradient Slide 3.27

87 Active Transport Processes Solute pumping Amino acids, some sugars and ions are transported by solute pumps ATP provides the energy to move substances against the concentration gradients Na/K Pump Slide 3.28a
