Question

how many molecules of carbon dioxide are produced when Krebs cycle operate twice? ⇒answer with detail

Answer 1

Answer:

Two molecules

Each turn of the Krebs cycle produces two molecules of carbon dioxide, one guano-sine triphosphate molecule (GTP), and enough electrons to generate three molecules of NADH and one molecule of FADH2.

Explanation:

Answer 2

Answer:

4

Explanation:

Each spherical of the Krebs cycle liberates  carbon dioxide molecules.

At the cease of the cycle all carbon atoms from the authentic glucose molecule degraded in glycolysis are already liberated integrated into the carbon dioxide molecules.

That happens due to the fact for every glucose  pyruvic acid molecules have been made with the aid of using glycolysis. Each of those  pyruvic acids then is transformed into acetyl CoA with liberation of 1 carbon dioxide molecule ( in total). Since every of the 2 produced acetyl CoA cycles the Krebs cycle once, from the preliminary glucose  rounds of the Krebs cycle is generated and so 4 different carbon dioxide molecules are made.

All of the six carbons of the glucose molecule are then integrated into six carbon dioxide molecules ( made at some stage in acetyl CoA formation and 4 at some stage in the 2 cycles of the Krebs cycle)carbon-dioxide-molecules-are-liberated-after-every-cycle-of-the-krebs-cycle.

So, if krebs cycle happen twice then 4 Co2 will realese.
