Edexcel A-Level Biology A2 7.4 Oxidative Phosphorylation Questions

Trace reduced-coenzyme electrons through the ETC, proton pumping and chemiosmosis, then explain ATP synthase and oxygen reduction to water using marked questions.

Exam points

identify cristae and the inner mitochondrial membrane as the electron-transfer site
trace electrons and proton pumping from reduced NAD or FAD through the transport chain
explain ATP synthase action and oxygen as the final electron acceptor forming water

Animals use aerobic and anaerobic respiration to produce ATP.

Aerobic respiration has three stages where reactions occur between enzymes and substrates.
