alleryIn aerobic respiration of one glucose, the number of CO2 released is
A6 CO2 per glucose molecule
B4 CO2 per glucose molecule
C2 CO2 per glucose molecule
D0 CO2 per glucose molecule
Answer & Solution
Correct answer: A. 6 CO2 per glucose molecule
2 CO2 from pyruvate to acetyl CoA (2 pyruvate per glucose) + 4 CO2 from two turns of the TCA cycle = 6 CO2 total.
Glycolysis produces no CO2. The 6 CO2 balance the 6 C of glucose.
