Answer:

Explanation: your the best

Kreb's cycle or citric acid cycle is the process in which CO₂ is released as a by-product of oxidation-reduction reactions.

We all know that the by-product of respiration is CO₂. The CO₂ is actually a by-product of an oxidation-reduction reaction that occurs in the mitochondria of all eukaryotic cells called the Kreb's cycle.

The Kreb's cycle is also called the citric acid cycle because the first product is usually citric acid. It is the second stage in cellular respiration, and is also called the aerobic stage, as it requires oxygen to occur. Since it requires oxygen, anaerobic organisms do not engage in the Kreb's cycle.

During glycolysis, one glucose molecule is broken down to give two pyruvate molecules, which concludes the first stage of cellular respiration. The pyruvate molecule is then taken to the matrix of the mitochondria, where the Kreb's cycle occurs and is decarboxylated to give CoA. Certain enzymes then break down the CoA to give two molecules of CO₂ as a by-product and one molecule of H₂O.
