Detailed explanation-1: -Pyruvate oxidation. Pyruvate travels into the mitochondrial matrix and is converted to a two-carbon molecule bound to coenzyme A, called acetyl CoA. Carbon dioxide is released and NADH is made. Citric acid cycle.

Detailed explanation-2: -CO 2 is created in the mitochondrial matrix during the TCA or Krebs cycle. Ingested nutrients in the form of glucose ( C 6 H 12 O 6 ) and oxygen are converted to energy in the form of adenosine triphosphate through cellular respiration (ATP). As a result of this reaction, CO 2 is created as a byproduct.

Detailed explanation-3: -Overview of the Krebs or citric acid cycle, which is a series of reactions that takes in acetyl CoA and produces carbon dioxide, NADH, FADH2, and ATP or GTP.

Detailed explanation-4: -During the first step of the citric acid cycle, the acetyl group from acetyl CoA is transfered to oxaloacetate to form citrate. Citrate then undergoes four more reactions to form succinate, along with producing two molecules of carbon dioxide, two molecules of NADH, and one ATP.

Detailed explanation-5: -The tricarboxylic acid (TCA) cycle, also known as the Krebs or citric acid cycle, is the main source of energy for cells and an important part of aerobic respiration. The cycle harnesses the available chemical energy of acetyl coenzyme A (acetyl CoA) into the reducing power of nicotinamide adenine dinucleotide (NADH).
