How many molecules of CO2 are in a single glucose molecule?

Answer 1

Glycolysis itself does not output CO2. Just after glycolysis the 2 pyruvates which are derived from the glucose molecule during glycolysis, are converted into 2 acetyl CoA in the process of which one CO2 per pyruvate is released.

After that the 2 acetyl CoA's enter the Kerbs cycle and a further 2 CO2's are produced for each.

In total 6 CO2's are created after glycolysis

• 2 during the conversion of pyruvates to Acetyl CoA
• 4 Durint the TCA/ Citric Acid/ Kerbs Cycle

Answer 2

It takes six molecules of CO2 to form one molecule of glucose. Plants use chloroplasts to make glucose molecules. It uses energy from the light reactions of photosynthesis to combine six water molecules to the six CO2.

The overall reaction is 6 CO2 + 6 H2O → 1 Glucose (C6H12O6) + 6 O2

Answer 3

If you are referring to the combustion of glucose (of which respiration is a variant) then there are 6 CO2 molecules released per glucose molecule.

Answer 4

None. Zero. Glucose molecule has 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms, but it does not contain any other molecules.

Answer 5

In the process of aerobic cellular respiration, one glucose molecule produces 6 molecules of carbon dioxide.

Answer 6

There are 6 carbon dioxide molecules.
