The next step of carbohydrate catabolism takes place in the . with the of coenzyme a, the 3-carbon molecules are converted to . this is the entry point for the , a 6-step process that harvests the chemical energy stored in carbohydrates in the form of high-energy electrons.

matrix of mitochondrion, pyruvate, acetyl CoA, citric acid cycle

Explanation:

After glycolysis, the next step of metabolism is in the matrix of mitochondrion. The pyruvate which is obtained as a product of the glycolysis got converted into two carbon molecule known as acetyl CoA with the help of coenzyme A.

Pyruvate is produced by the glycolysis in cytoplasm. The oxidation of pyruvate takes place in mitochondrial matrix.  

Pyruvate is converted to acetyl-CoA in the reaction given below:

Pyruvate + NAD⁺ + CoA-SH ⇒ acetyl-CoA + NADH + CO₂

This acetyl CoA enters the citric acid cycle which is a 6 -step process.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.
