Question

Which process of cellular respiration takes place in the cytosol of the cell?

• A. Krebs cycle
• B. Glycolysis
• C. Electron transport chain
• D. Oxidative phosphorylation
• E. Calvin cycle

Answer 1

Answer: (B)

Glycolysis

A. In eukaryotes, Krebs cycle takes place in the matrix of the mitochondrion whereas, in prokaryotes, Krebs cycle takes place in the cytoplasm.

B. In prokaryotes as well as eukaryotes, Glycolysis takes place in the cytoplasm.

C. Electron transport chain is present in the inner membrane of the mitochondrion in eukaryotes and in the cellular membrane of prokaryotes.

D. Oxidative phosphorylation occurs on the inner membrane of the mitochondrion and the inner side of the cell membrane or mesosomes in prokaryotes.

E. Calvin cycle or C3 pathway is the process of CO₂ reduction that occurs in the plants during the dark phase of photosynthesis.

So, the correct answer is Glycolysis.
