Which of the following statements about glycolysis is correct?

Correct option is D

The correct answer is (d) It takes place in cytoplasm

Explanation:

• Glycolysis is the first step of cellular respiration, occurring in both aerobic and anaerobic organisms.
• It takes place entirely in the cytoplasm of the cell.
• During this process, one molecule of glucose (6-carbon) is broken down into two molecules of pyruvic acid (3-carbon).
• It does not require oxygen to proceed.

Information Booster:

• Glycolysis yields a net gain of 2 ATP and 2 NADH molecules per glucose molecule.
• It is also known as the EMP pathway (after Embden, Meyerhof, and Parnas).

Additional Knowledge:

It occurs in mitochondria (Option a)

• The Krebs Cycle and Electron Transport Chain occur in the mitochondria, not glycolysis.

It produces carbon dioxide (Option c)

• CO₂ is produced during the Link Reaction and the Krebs Cycle, not during glycolysis.

So the correct answer is (d)
