Question

question: which of these is a stage in anaerobic respiration? answer options: select one of four the electron transport chain the krebs cycle pyruvate oxidation glycolysis

Explanation:

To determine the stage in anaerobic respiration, we analyze each option:

• The electron transport chain: Requires oxygen, part of aerobic respiration.
• The Krebs cycle: Requires oxygen, part of aerobic respiration.
• Pyruvate oxidation: Requires oxygen, part of aerobic respiration.
• Glycolysis: Occurs in the cytoplasm, does not require oxygen, and is the first stage of both aerobic and anaerobic respiration.

Answer:

D. Glycolysis
