Question

Which statement best describes the process of chemiosmosis and the direct result of its occurrence?

Answer 1

The choices are Hydrogen ions flow from the thylakoid down a concentration gradient through ATP synthase channels into the stroma. ADP is converted to ATP.
Hydrogen ions flow from the thylakoid down a concentration gradient through ATP synthase channels into the stroma. ATP is converted to ADP.
Hydrogen ions flow from the stroma down a concentration gradient through ATP synthase channels into the thylakoid. ADP is converted to ATP.
Hydrogen ions flow from the thylakoid against a concentration gradient through ATP synthase channels into the stroma. ADP is converted to ATP.

Answer 2

Taken from Quizlet:
What effect would an absence of O2 have on the process shown in Figure 9.16? Oxidative phosphorylation would stop entirely, resulting in no ATP production by this process. Without oxygen to "pull electrons down the electron transport chain, H+ would not be pumped into the mitochondrion's intermenbrane space and chemiosmosis would not occur.

In the absence of O2, as in the question above, what do you think would happen if you decreased the pH of the intermembrane space of the mitochondrion? Explain your answer. Decreasing the pH is the addition of H+. It would establish a proton gradient even without the function of the electron transport chain, and we would expect ATP synthase to function and synthesize ATP. (In fact, it was experiments like this that provided support for chemiosmosis as an energy-coupling mechanism.)

Idk if this will help since I don't know much about Chemiosmosis :$
