2 NADH and 1 FADH2 two;
1 NADH and 1 FADH2 four;
3 NADH and 1 FADH2 four;
2 NADH and 2 FADH2

Answer 1

Four; 3 NADH and 1 FADH2

Step-by-step explanation:

• Each turn of the citric acid cycle generates one ATP and four additional energy-rich molecules: 3 NADH and 1 FADH2.
• The citric acid cycle is one of the three phases of cellular respiration together with glycolysis and electron transport chain.
• The citric acid cycle is the second phase of cellular respiration. This phase yields carbon dioxide, water, ATP and electron carriers NADH and FADH2.
• The electron carriers (FADH2 and NADH) are then taken to the electron transport chain (last phase of cellular respiration) to yield more energy in the form of ATP.
