Question

Choose the correct answers from the alternatives given :
One turn of the Krebs cycle produces

• A. 2 NADH, 2 $FAD{H}_2$, 2 ATP
• B. 3 NADH, 1 $FAD{H}_2$, 1 ATP
• C. 1 NMDH, 3 $FAD{H}_2$ , 2 ATP
• D. 3 NADH, 2 $FAD{H}_2$, 1 ATP

Answer 1

The correct option is B 3 NADH, 1 $FAD{H}_2$, 1 ATP

Krebs cycle is also called the citric acid cycle which has a series of eight reactions like oxidative decarboxylation, oxidation, hydration, rehydration etc. Each turn of the Krebs cycle produces 1 GTP ( ATP ) molecule, 3 NADH and 2 FADH${}_2$ molecules, which is used for the process of cellular respiration to occur and produce energy.

So , correct option is ' 3 NADH , 1 FADH${}_2$ , 1 ATP ' .
