Answer True or False for all of the following questions: 1a. Hyperpolarizing the plasma membrane by increasing the activity of the plasma membrane H+-ATPase will promote passive accumulation of chloride ion (Cl-) in the cell. 1b. The Calvin Benson Cycle is active during the day in C3, C4, and CAM plants. 1c. Rubisco is more likely to perform the oxygenase reaction during the night than during the day. 1d. Increasing the chloroplast lumen pH will activate processes that reduce the production of singlet oxygen. 1e. On a volume basis, phloem contents have more energy than the xylem contents.

For the following question: True = 1 False = 2 Are the following statements true or false? 1. ATP is constructed within the electron transport chain 2. Photosynthesis occurs in the mitochondria of the cells: 3. Photosynthesis is an anabolic process Note: anabolic: the synthesis in living organisms of more complex substances from simpler ones

Question 1 True or False: In the light-dependent reactions of photosynthesis, H2O gets oxidized. True False QUESTION 2 True or False: Hydrolysis of ATP is more exergonic than oxidation of FADH2. True False QUESTION 3 True or False: The energy released by oxidation of NADH in the electron transport system is used to pump protons up their gradient. Protons flowing down their gradient are in turn used to provide the energy for phosphorylation of ADP. True False QUESTION 4 True or False: The combined reactions of photosynthesis are essentially the reverse of the combined reactions of glucose catabolism, with the exception that ATP is a product of glucose catabolism, but neither a net reactant or product of the combined reactions of photosynthesis. True False
