Question

Single turn of citric acid cycle yields

• A. 2 $FAD{H}_2$, 2$NAD{H}_2$, 2GTP
• B. 1 $FAD{H}_2$, 2$NAD{H}_2$, 1GTP
• C. 1 $FAD{H}_2$, 3$NAD{H}_2$, 1GTP
• D. 1 $FAD{H}_2$, 4$NAD{H}_2$, 1GTP
• E. 1 $FAD{H}_2$, 1$NAD{H}_2$, 2GTP

Answer 1

The correct option is C 1 $FAD{H}_2$, 3$NAD{H}_2$, 1GTP

The citric acid cycle is a series of chemical reactions in the aerobic condition generates chemical energy through the oxidation of acetyl-CoA into carbon dioxide. Each turn of the cycle forms one GTP as well as three NADH2 molecules and one FADH2 molecule, which will be used in further steps of cellular respiration to produce ATP for the cell. Hence, option C is correct.
