Total questions: 9
Worksheet time: 5mins
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
