Question

Net yield of ATP molecules in 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

Krebs' cycle involves 8 stpes to oxidise 2 molecules of acetyl Co-A produced in transition reaction completely into 4 CO2, 10 H2O, 2 ATP (or GTP), 2 FADH2, and 8 NADH.
