When is carbon dioxide released in cellular respiration?

Answer 1

In anaerobic respiration CO2 is release in fermentation (in cytoplasm) but never during glycolysis. Also. It isnot formed during lactic acid fermentation. Only 2CO2 are formed per glucose molecule in fermentation.

In aerobic respiration, total 6Co2 molecules are generated per glucose molecule. 2Co2 during transition reaction i.e. during oxidative decarboxylation of pyruvate to acetyl CoA in mitochondrial matrix. And remaining 4Co2 are formed during Kreb's cycle. 2Co2 are released between the conversion of oxalosuccinate to alpha keto glutarate and other 2Co2 from oxidative decarboxylation of alpha keto glutarete to alpha keto glutarate.

Answer 2

Carbon dioxide is released during two phases of cellular respiration. The first phase that carbon dioxide leaves is during pyruvate decarboxylation. The second time CO2 is released is during the Kreb's cycle. 1 CO2 leaves during the decarboxylation and two leave during the Kreb's cycle. Since there are two pyruvate per glucose molecule, everything happens twice. This makes a total of 6 CO2 released per glucose molecule.

Answer 3

oxidation of pyruvate to acetyl CoA and the citric acid cycle

Answer 4

CO2 is released during the formation of Acetyl CO A (2) and the Krebs Cycle (4).

Answer 5

CO2 is released at the stomata under the leaf.

Answer 6

CO2 is released in kreb cycle.Six CO2 are produced.
