Microcheck

Respiration uses the NADH and FADH2 generated in glycolysis, the transition step, and the TCA cycle to synthesize ATP. The electron transport chain is used to convert reducing power into a proton motive force. ATP synthase then harvests that energy to synthesize ATP. The overall process is called oxidative phosphorylation. In aerobic respiration O2 serves as the terminal electron acceptor; anaerobic respiration employs a molecule other than O2.

■ Why is the overall ATP yield in aerobic respiration only a theoretical number?

■ In bacteria, what is the role of the molecule that serves as a source of vitamin K for humans?

■ Why could an oxidase also be called a reductase?
