2) What makes up an ADP molecule? Adenine, ribose sugar, two phosphate groups Adenine, ribose sugar, three phosphate groups Ribose sugar, adenine, one phosphate group 0 of 30

3) What light-absorbing molecules collect the sun’s energy for plants? Thylakoids Chloroplasts Glucose Pigments 0 of 30

4) Which of the following is true about light-dependent reactions? It absorbs green light and makes sugars. It occurs after the Calvin Cycle. It only occurs in the dark. It produces energy (ATP & NADP+) that is used in light-independent reactions. 0 of 30

5) Which is a product of the light-independent reactions? Carbon dioxide Oxygen High-energy sugars (glucose) ATP and water 0 of 30

6) What type of process is cellular respiration? Anabolic Catabolic Fermentation Respiration

7) What order will these processes occur if oxygen is present? Electron Transport, Chain Krebs, Cycle Glycolysis Glycolysis, Krebs Cycle, Electron Transport Chain Glycolysis, Fermentation, Krebs Cycle Krebs, Fermentation, Glycolysis

8) Does cellular respiration occur in plant and animal cells? Yes No

9) What is oxygen’s purpose in cellular respiration? It combines with water. It is the final electron acceptor for the electron transport chain. It produces light and heat. It donates electrons to help us breathe in the Krebs Cycle.

10) Which processes occur in the cytoplasm? Calvin Cycle Krebs Cycle Electron Transport Chain Glycolysis

11) What are the products in photosynthesis? Carbon dioxide, water, energy (sunlight) Oxygen, carbon dioxide, glucose, water ATP and water Glucose and oxygen

12) What are the products in respiration? Carbon dioxide, water, energy (ATP) Oxygen, carbon dioxide, glucose, water ATP and water Glucose and oxygen

13) What is an example of an electron carrier? Pyruvic acid ATP NAD+ & NADPH AMP

14) The electrons transported along the membrane in the electron transport chain are used to make Lactic acid Oxygen ATP Glucose

15) Breaking off a phosphate group from ATP results in the absorption of energy the creation of energy the production of mechanical energy the release of energy

16) This diagram shows the relationship between ATP and AMP. True False

Water flowing downstream Photosynthesis Glycolysis 17) Which example shows chemical energy converted to mechanical (movement) energy? Water flowing downstream Photosynthesis Glycolysis Contracting a muscle

Carbon dioxide Glucose ATP Water 18) When oxygen is used in the electron transport chain, what does it become? Carbon dioxide Glucose ATP Water
