1.
Why does reduced FAD yield fewer ATP than reduced NAD?
It carries fewer electrons
It is made in the cytoplasm
It is not oxidised
It donates electrons further along the ETC so fewer protons are pumped
2.
Which statement best describes NAD+?
Direct transfer of a phosphate from a substrate molecule to ADP to form ATP.
ATP synthesis powered by the electron transport chain and chemiosmosis.
An electron carrier coenzyme that is reduced to NADH by accepting 2 electrons and a proton.
The Krebs cycle: oxidation of acetyl CoA to CO2 in the matrix, producing NADH, FADH2 and ATP.
