In what stage of cellular respiration is most of the carbon dioxide produced? A. glycolysis B. fermentation C. citric-acid cycle D. electron transport chain

Respuesta :

Answer;

C. citric-acid cycle

Explanation;

-Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate.

-The citric acid cycle is a series of reactions that produces two carbon dioxide molecules, one GTP/ATP, and reduced forms of NADH and FADH2. Because two acetyl-CoA molecules are produced from each glucose molecule, two cycles are required per glucose molecule. Therefore, at the end of two cycles, the products are: two GTP, six NADH, two QH2, and four CO2.

Citric acid cycle is the stage of cellular respiration that produce most of the carbon dioxide.

The correct option is (C)

What is citric acid cycle?

Citric acid cycle also known as Krebs cycle is a process to release the saved energy through oxidation of acetyl-CoA derived from proteins, carbohydrates, and fat.

Krebs cycle is a key process for the metabolism of proteins, fat and carbohydrates.

The process is completed in ten steps with the help of eight enzymes.

Thus, the option (C)citric-acid cycle is correct.
