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.

lunar landing mission. apollo 11 was the first manned mission to land on the moon. the first steps by humans on another planetary body were taken by neil armstrong and buzz aldrin on july 20, 1969. the astronauts also returned to earth the first samples from another planetary body.
