5 2-1 The Nature of Matter Elements and Isotopes What is an element's mass number (atomic mass)? What are isotopes? Why are most atomic masses reported on the periodic table decimals (not whole numbers)? Explain why/how this atom is especially important for life as we know it and the study of biology. 5

Do isotopes have the same number of electrons? Do isotopes have the same chemical properties (bond with other atoms the same)? What makes some isotopes radioactive? What are 4 ways radioactive isotopes are scientifically useful? 6

11 2-2 Properties of Water As for most molecules, the + and charges in a water molecule are equal so that overall the molecule is? However, note that the molecule is not linear. How would you describe the molecule in terms of shape and the positions of the types of atoms, or elements? Considering the number of positively charged protons in the nuclei of each atom, which would you predict has a greater affinity (attraction) for electrons?

Each water molecule is capable of interacting with how many other water molecules in this way? Compare and contrast this type of bonding with ionic bonding, covalent bonding and Van der Waals forces, in terms of strength and what is being bound. Label + and regions and the hydrogen bonds of the model above. 12

13 2-2 Properties of Water Cohesion More magical properties due to the polarity of water! Explain how polarity and hydrogen bonding makes water cohesive. Explain how cohesion produces water's surface tension that can support a microecosystem known as the surface film. 13

14 2-2 Properties of Water Adhesion Due to polarity, water molecules are not only able to hydrogen bond with each other, but other molecules too! What is this property called?

What are polysaccharides? Give 2 examples, along with where they are found and function. Note that the names of all carbohydrate molecules typically end in ose (Good to remember!). 29

30 2 3 Carbon Compounds Lipids What are the 4 classes of lipids? Lipids are composed mostly of which 2 elements? As a result, unlike water, they are not and therefore not in water, meaning they will not dissolve. This allows lipids to function as waterproof barriers, like cellular, and coverings, like the leaf. Describe the structure of a triglyceride using the terms glycerol and fatty acids. 30

31 2 3 Carbon Compounds Lipids Compare the two fatty acids. Identify 3 differences. The one on the left is making it at room temperature (fat). The one on the right is, making it at room temperature (oil). Use this knowledge to describe a fatty acid that is polyunsaturated. 31

What are the elements or compounds produced by a chemical reaction called and on which side of a chemical equation are they found? In the example reaction, what are the reactants and what is the product? In the chemical equation, what do the numbers in front of the elements and compounds do for the equation? 38

39 2 4 Chemical Reactions and Enzymes Energy in Reactions Breaking and forming bonds requires changes in. Define exergonic reaction, and give an example. Define endergonic reaction and give an example. In order to stay alive, organisms must perform endergonic reactions. What is the ultimate source of energy for these reactions?

Trace the flow of energy from the ultimate source to the endergonic reactions keeping you alive. 39

40 2 4 Chemical Reactions and Enzymes Energy in Reactions Identify and label the graphs representing an endergonic vs. exergonic reaction. The energy available for a reaction (y-axis) is energy (heat). This increases the energy (movement) of reactants. Note that BOTH endergonic and exergonic reactions require activation energy. Define activation energy. What characteristic of this type of graph can be used to identify endergonic vs. exergonic reactions? 40

41 2 4 Chemical Reactions and Enzymes Energy in Reactions Some chemical reactions occur too slowly or have activation energies too high for living systems. Define enzymes, and explain how they solve this problem. Study the graph and relate what it illustrates to what enzymes are and do. Enzymes are very specific to the reactions they catalyze. How are they usually named? Give one example of an enzyme and the reaction it catalyzes. 41

42 2 4 Chemical Reactions and Enzymes Enzyme Activity Study this example of an enzyme catalyzed reaction and write the chemical equation using names, not chemical formulas. What are the reactants of an enzyme catalyzed reaction called? Note the region of the enzyme where the substrates fit. What is this region called and how is it important? What is a metaphor for how the substrates fit in the active site? Define enzyme-substrate complex. Note that the diagram is cyclical, illustrating that enzymes are! 42
