The Krebs cycle takes place in the mitochondria of cells when adequate oxygen is present. Which substance is a product of the Krebs cycle?

for one molecule of glucose in Kreb cycle the products are

2 ATP molecule

4C02

6NADH

2FADH2

NADH, FADH2, and ATP or GTP.

Explanation:

Citric acid cycle refers to the different chemical reactions that is engaged by all aerobic organisms in order to release the energy stored through the oxidation of acetyl-CoA that is gotten from proteins, fats and carbohydrates, into adenosine triphosphate (ATP) and carbon dioxide (CO2). It is also called TCA cycle or the Krebs cycle.

The first step of citric acid cycle starts with the fusion of acetyl-CoA and oxaloacetate to produce citric acid. And the products of the citric acid cycle for each acetyl-CoA molecule contains these products;

1.) carbon dioxide molecules

2.) Three NADH molecules

3.) One FADH2 molecule, and one GTP/ATP molecule.

Therefore, for every When a glucose molecule to produce two acetyl-CoA molecules, there will be production of 4 carbon dioxide molecules (CO2), 6 NADH molecules, 2FADH2 molecules, and 2 GTP/ATP molecules by the cytric acid cycle. There is also regeneration of oxaloacetate by the cytric cycle.

The citric acid cycle is cycled twice for all glucose molecules that goes through respiration. and for each glucose, there is production of two acetyl-CoA molecules
