Question

Q1. ATP synthase:

a) is often described as a molecular motor

b) is bound by the inhibitor oligomycin on the F1 subunit

c) contains a F1 "knob" that, when dissociated from the F0 portion, can synthesize ATP from ADP and Pi

d) dissociation with urea blocks further O2 use.

Q2. The mitochondrial ATP synthase:

a) has no moving parts

b) catalyzes ATP synthesis through pumping ATP out of the matrix, decreasing the ATP/ADP ratio

c) uses the energy stored in the proton gradient to drive conformational changes in the F1 component beta-subunit (ATP synthase)

Q3. When a glucose molecule is broken down to CO2 in glycolysis and the TCA cycle, little ATP is directly produced, most of the energy is:

a) stored as pyruvate

b) lost as heat

c) stored as NADH

d) stored as CO2
