Question

Glycolysis process occurs in which part of the cell?

• A. Cytoplasm
• B. Nucleus
• C. Mitochondria
• D. Chloroplast

Answer 1

The correct option is A

Cytoplasm

The correct option is A.

Explanations of correct option:

Option A:

1. Glycolysis is a sequential process of breakdown of glucose in the presence of oxygen to synthesize ATP.
2. ATP (Adenosine triphosphate) is the energy source for all bodily reactions.
3. The location of the glycolysis process in the cytoplasm of the cell.
4. Pyruvate is the end product of the glycolysis cycle.

Explanations of incorrect options:

Option B:

1. The nucleus is associated with the DNA replication process.
2. The genetic information of the cell is found in the nucleus.
3. The transcription process also occurs inside the nucleus, which is the formation of mRNA (messenger RNA) from DNA for protein production.

Option C:

1. Another name for mitochondria is the energy house of the cell, as it helps in the production of energy-rich ATP molecules.
2. Oxidative phosphorylation is the process occurring at the inner mitochondrial membrane involving the production of ATP molecules based on the proton pump.
3. The citric acid cycle also occurs inside the mitochondria.
4. The citric acid cycle also produces energy-rich molecules such as ATP, NADH, and FADH2.

Option D:

1. Chloroplast is associated with the metabolic conversion of light energy into chemical energy.
2. It harvests the light energy of the sun to produce glucose molecules.
3. The photosynthesis process occurs in the chloroplast.

Final answer: The Glycolysis process occurs in the cytoplasm of the cell.
