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)
