Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The number of ATP molecules produced out of Krebs Cycle for 1 molecule of glucose is:
A
2
B
3
C
4
D
0
Explanation: 

Detailed explanation-1: -In total 30 ATP molecules are produced per glucose. So, the correct answer is option (C) 30. Note:-The actual ATPs produced by one molecule of glucose are 32 but 2 molecules of ATP are used during the initial stages of glycolysis.

Detailed explanation-2: -The net energy output for one glucose molecule from glycolysis through the Krebs cycle is: 4 ATP, 10 NADH + H+, and 2 FADH2.

Detailed explanation-3: -In a eukaryotic cell, the process of cellular respiration can metabolize one molecule of glucose into 30 to 32 ATP.

Detailed explanation-4: -2 ATPs are produced in the TCA cycle per glucose molecule (2 acetyl CoA).

Detailed explanation-5: -Krebs cycle produces the following: Two molecules of carbon dioxide are given off. One molecule of ATP is formed.
