How many of glucose carbons are converted t co2 at the end of aerobic respiration?

Answer 1

6 molecules. 2 molecules of 3 carbon containing pyruvic acid enter the glycolytic stage via a 2 carbon acetyl coA each producing 3 CO2 per cycle. Glucose contains 6 carbons so only 6 available for CO2.

Answer 2

During aerobic respiration, each glucose molecule is converted to two molecules of pyruvate, with a total of 6 carbons. These two pyruvate molecules are then converted to acetyl-CoA, which enters the citric acid cycle and is eventually fully oxidized into carbon dioxide, releasing a total of 6 molecules of CO2.

Answer 3

6
