1 Cellular Respiration and Photosynthesis
2 processes are the chemical processes that occur in all living things. Two of these processes are and. They are both controlled by. is carried out by organisms. is carried out by and some singlecelled organisms. Euglena
3 II. Cellular Respiration: You learned that when you eat foods that are carbohydrates (bread and pasta) they are broken down by your. They are broken down into (glucose) The bonds of glucose are then broken by a series of to form energy. This energy is captured into the bonds of the High Energy Molecule known as (Adenosine Triphosphate) This energy is used by the organism for it s
4 Diagram of ATP II A. The ATP/ADP Cycle: ATP and ADP are compounds that are found in all cells. The D in ADT is for Diphosphate or phosphates. The T in ATP is for Triphosphates or phosphates. ADP and ATP are converted back and forth as a is added or removed.
5 We get energy to put the third phosphate on to ADP by burning. The most common food that is burned is.
6 ATP 100% Renewable Energy All living things rely on one source of energy to do all things from building molecules to flexing muscles = ATP (Adenosine Triphosphate). Breaking down ATP releases energy and cells constantly replace their ATP by attaching a spare phosphate onto ADP. The energy from that comes from food we eat (animals) or make (plants). Enzymes control the breaking and making of ATP
7 II. B Two Types of Respiration: There are two ways to burn glucose (two types of respiration) Anaerobic Respiration does NOT use. This is also called. Aerobic Respiration USES II. C Anaerobic Respiration (fermentation) Some cells lack the necessary for aerobic respiration and other cells like your muscle cells change to anaerobic respiration when oxygen is lacking
8 The enzymes necessary for this type of respiration are located in the of the cells. In Anaerobic respiration is partially broken down by the to form either or and. Both of these form only ATP molecules. and cells form the lactic acid and 2 ATP. form the alcohol and carbon dioxide and 2 ATP. Glucose Glucose or 2 Lactic Acid + 2 ATP 2 alcohol + 2CO 2 + 2ATP
9 II D. Aerobic Respiration: Most organisms are more complex and need more to perform their life activities than anaerobic respiration can produce. Aerobic respiration occurs in the cell organelle called the.
10 In Aerobic Respiration is completely broken down in a series of controlled reactions to form and and ATP molecules ATP
11 II E. Comparison Chart for Aerobic and Anaerobic Respiration Anaerobic Respiration Aerobic Respiration 1. Takes place in the Takes place in the 2. No Requires 3. Less efficient ( ATP) More efficient ( ATP) 4. Waste products: or and. Waste products: and 5. Time frame: Time frame: 6. Glucose breakdown is Glucose breakdown is.
12 III. Photosynthesis: The energy for life primarily comes from the. Photosynthesis is biochemical food-making process that provides a connection between the and needs of living things. During solar energy is used to combine molecules of and into energy rich organic compounds such as.
13 This process releases into the environment. Photosynthesis is a type of nutrition called nutrition. III A. Location for Photosynthesis Green cells and and some celled organisms contain this organelle is involved in the process of. are located mainly in the of green plants.
14 are located in the cytoplasm and contain the green pigment. along with are necessary for the food-making process of. The is considered the food factory of photosynthetic plants. The leaf has many that make it well adapted for the process of photosynthesis
15 A. Leaves are arranged on stems, so that they can receive the maximum absorption B. Leaves have and for gas exchange. C. The majority of chloroplasts are located in the. D. are bean shaped structures located around stomates which contain and the opening and closing of the stomates.
16 Leaf cross section Stomata and guard cells
17 III b. Chemistry of Photosynthesis: Photosynthesis involves in which and are converted into sugar molecules. gas is a by-product. Besides photosynthesis also requires and.
18 Sexy Sally Sun Phyll the Chlorophyll Molecule Splits H2O to give off O NADP Train A carrier molecule that picks up H2 and combines It with CO2 to make PGAL, a sugar which will then Form the sugar glucose
19 III c. Factors that influence The Rate of Photosynthesis: Photosynthesis occurs best at 35 0 Celsius. Above this the enzymes are destroyed (denatured) intensity. increases the rate up to a point. shortage decreases photosynthesis.
