Question

level 4 q1 what is the electron transport chain also known as? a. fermentation b. oxidative phosphorylation c. glycolysis d. krebs cycle a. fermentation b. oxidative phosphorylation c. glycolysis d. krebs cycle

Explanation:

• Option A: Fermentation is an anaerobic process to produce ATP, not related to the electron transport chain.
• Option B: The electron transport chain is part of oxidative phosphorylation, where ATP is synthesized using energy from electron transfer.
• Option C: Glycolysis is the initial breakdown of glucose, separate from the electron transport chain.
• Option D: The Krebs Cycle (Citric Acid Cycle) produces electron carriers for the electron transport chain, but is not the chain itself.

Answer:

B. Oxidative phosphorylation
