Question

cellular respiration oxygen is an important molecule in which of the following? glycolysis, citric acid cycle, and electron transport chain citric acid cycle only glycolysis only citric acid cycle and electron transport chain electron transport chain only

Explanation:

In cellular respiration, oxygen is the final electron - acceptor in the electron transport chain. The citric acid cycle also requires oxygen indirectly as it depends on the products of the electron transport chain for its continuous operation. Glycolysis is an anaerobic process and does not require oxygen.

Answer:

Citric acid cycle and electron transport chain
