Oxidative Phosphorylation

How does the electron transport chain facilitate the synthesis of ATP?

• The ATP is synthesized by the ATP synthase found in the electron transport chain

• The ATP synthesized at the end of the electron transport chain

• The ATP is synthesized by the protons combing with the oxygen in the electron transport chain

• The ATP is synthesized by the protons flowing down their concentration gradient after being pumped out by the ETC

How many ATPs are synthesized from the energy carried by NADH and FADH2 (on average)?

• 1 NADH = 2 ATP; 1 FADH2 = 1 ATP

• 1 NADH = 2 ATP;  1 FADH2 = 3 ATP

• 1 NADH = 1 ATP; 1 FADH2 = 1 ATP

• 1 NADH = 3 ATP;  1 FADH2 = 2 ATP
