When one molecule of glucose is completely oxidised during aerobic respiration, how many molecules of carbon dioxide are released due to tricarboxylic acid cycle?

Question

When one molecule of glucose is completely oxidised during aerobic respiration, how many molecules of carbon dioxide are released due to tricarboxylic acid cycle? (A) One (B) Two (C) Three (D) Four

Tardigrade Admin · Accepted Answer

The one turn of the citric acid cycle releases two carbon dioxide molecules and produces three NADH, one FADH2, and one ATP or GTP. As the cycle turns twice so the number of CO 2 molecule produce will be 2 X 2=4 molecules. So the correct option is ' 4 '.

The one turn of the citric acid cycle releases two carbon dioxide molecules and produces three NADH, one FADH2, and one ATP or GTP. As the cycle turns twice so the number of $C O_{2}$ molecule produce will be $2 X 2 = 4$ molecules. So the correct option is ' 4 '.
