Answer 1

7.) During the light reactions of photosynthesis, electrons move from photosystem II to photosystem I and fall to a lower energy level. Which of the following do you predict would happen if cells had only one photosystem?

A.) A different electron acceptor would be needed before the Calvin cycle.
B.) A proton gradient would be created across the thylakoid membrane.
C.) Electrons would not gain enough energy to enter the electron transport chain.
D.) The energy needed to synthesize ATP from ADP would not be produced.


10.) A biochemical reaction has the following values relating to energy flow:

T = 473K
∆S = 1.11 kJ/K
∆H = -704kJ

Which of the following statements is true about this reaction?

A.) The reaction is always spontaneous.
B.) The reaction is never spontaneous.
C.) The reaction is spontaneous only when ATP is coupled to it.
D.) The reaction is spontaneous only when the temperature is above 0°K.

11.) Within an organism, both spontaneous and non-spontaneous chemical reactions take place to meet the needs of the organism. Describe how an organism would be affected, in terms of free energy and entropy, if only spontaneous reactions occurred.


12.) During the process of cellular respiration, one molecule of glucose is capable of producing up to 32 molecules of ATP. Explain the mechanism by which ATP is produced by ATP synthase. Be sure your answer describes the structural features involved in this process.
