Precisely, it is called pyruvate decarboxylation. The COOH group Pyruvate is removed as CO2, and Acetyl CoA from Coenzyme A is added in an NAD+ dependent manner by the enzyme decarboxylase.
Acetyl-CoA is formed when Coenzyme A attaches to 2 carbons from pyruvic acid. Acetyl-CoA is an important molecule that enters the citric acid cycle to produce energy through the oxidation of acetyl groups.
The coenzyme FAD is formed from vitamin B2, also known as riboflavin.

Pyruvic acid is converted into acetyl CoA before it enters the citric acid cycle. Acetyl CoA combines with oxaloacetate to form citrate, initiating the citric acid cycle. This cycle is essential for extracting energy from carbohydrates through a series of redox reactions.
This reaction forms acetyl CoA, which is a crucial molecule in cellular respiration. Acetyl CoA enters the citric acid cycle to generate ATP through oxidative phosphorylation. This process occurs in the mitochondria of eukaryotic cells.
Pyruvic acid is formed in glycolysis.
Acetyl coenzyme A is formed from the breakdown of carbohydrates, fats, and proteins in the cell. These molecules are converted into acetyl CoA through various metabolic pathways such as glycolysis, fatty acid oxidation, and amino acid catabolism. Acetyl CoA then enters the citric acid cycle to generate energy in the form of ATP.
When pyruvic acid enters the mitochondria, it undergoes a process called decarboxylation, where it is converted into acetyl-CoA. During this process, carbon dioxide (CO2) is released as a byproduct. This CO2 is the gas formed when pyruvic acid is metabolized in the mitochondria.

One molecule of glucose stores more potential energy than two molecules of pyruvic acid because glucose has more carbon-hydrogen bonds, which can be broken down to release energy through cellular respiration. Pyruvic acid is an intermediate product of glucose metabolism and has already undergone some breakdown, resulting in a lower energy content.
Carbon dioxide and water are the chemicals formed by the aerobic breakdown of glucose through the process of cellular respiration. This process generates energy in the form of ATP for the cells to use.
