Question

which process occurs in the cells cytoplasm and does not require oxygen? a the electron transport chain b glycolysis c the krebs cycle

Explanation:

• Electron transport chain: Occurs in the inner mitochondrial membrane and requires oxygen as the final electron acceptor.
• Glycolysis: Takes place in the cytoplasm. It is an anaerobic process (does not require oxygen) that breaks down glucose into pyruvate.
• Krebs cycle: Occurs in the mitochondrial matrix and is part of aerobic respiration (indirectly requires oxygen as it depends on the electron transport chain which needs oxygen).

Answer:

B. glycolysis
