Answer #1

The electron transport chain consists a sequence of organic molecules and proteins which transport the electron released by the NADH and the FADH2. It generates a proton gradient and the proton is finally reached to the ATP synthetase, which generates the ATP molecules.

So, when the chain blocker is present, the process stops.

In this case there will be electron release by the NADH, so it's concentration in the matrix increases.

So the correct option is B.

The glycerol-3-phosphate shuttle can transport cytosolic NADH equivalents into the mitochondrial matrix (see Fig. 15.11c). In this shuttle, the protons and electrons are donated to FAD, which is reduced to FADH2. These protons and electrons are subsequently donated to coenzyme Q in the electron transport chain. Given that the number of ATP molecules made per NADH and FADH2 oxidation differ by ____? the amount of ATP generated per mole of glucose when the glycerol-3-phosphate shuttle would be ____ instead of...
