Which of the following statements concerning ATP synthesis is NOT true?
a.
The open conformation of the ATP synthase is for releasing ATP.
b.
The gamma subunit in the stalk responds to the flow of H+ and rotates the assembly counterclockwise and thus change the conformations of the active site to synthesize ATP.
c.
The tight conformation of the ATP synthase is for converting ADP and phosphate to ATP.
d.
The loose conformation of the ATP synthase is for binding ADP and phosphate.
e.
Ten protons are required to catalyze the rotation of the subunits so that one ATP is synthesized.

For each of the statements below, indicate whether they are true or false and then in detail
explain why the false statements are incorrect, making reference to the relevant cell processes
and/or molecules.
A. In cellular respiration the ETC transfers electrons via redox reactions whereas in
photosynthesis the ETC transfers electrons using light.

outer side of the inner membrane whereas in photosynthesis the ETC creates a proton gradient
with the higher concentration on the inner side of the thylakoid membrane.
C. In cellular respiration the ETC gradient is used to power ATP production by oxidative
phosphorylation whereas in photosynthesis the ETC gradient is used to power ATP production
