Question

Net yield of aerobic respiration during Krebs cycle per glucose molecule is

• A. 2 ATP molecules
• B. 8 ATP molecules
• C. 36 ATP molecules
• D. 38 ATP molecules

Answer 1

The correct option is A 2 ATP molecules

The tricarboxylic acid cycle is a series of chemical reactions to generate energy through the oxidation of acetyl CoA. During one cycle, one molecule of ATP is produced when succinyl-CoA gets converted into succinic acid. Since for 1 molecule of glucose 2 rounds of Krebs cycle occurs, there is the net yield of 2 ATP molecules.
