Answer:
The correct answer is 32.
Step-by-step explanation:
Glycolysis, citric acid cycle, and oxidative decarboxylation of pyruvate are the processes that take part in the complete oxidation of 1 molecule of glucose to carbon dioxide and the oxidation of all the reduced coenzymes. In the process of glycolysis, a total of 2 NADH and 2 ATP are produced. Each of the NADH further produces 2.5 molecules of ATP. Therefore, 2 NADH will produce, 2 * 2.5 = 5 molecules of ATP. Thus, the total ATP produced during glycolysis is 2+5 = 7.
In the citric acid cycle, 2 ATP, 2 NADH, and 2 FADH2 molecules are produced. Further, each NADH produces 2.5 ATP and each FADH2 produces 1.5 molecules of ATP, Thus, the total ATP produced would be,
6*2.5 + 2 + 2*1.5 = 20
In the process of oxidative decarboxylation, two molecules of NADH are produced, thus, total ATP produced would be,
2*2.5 = 5
Therefore, in the complete transformation of 1 glucose molecule to carbon dioxide and the oxidation of all the reduced coenzymes, the number of ATP produced will be,
= 7+20+5 = 32
