Question

what do aerobic respiration and anaerobic respiration have in common?
both begin with glycolysis.
both occur in mitochondria.
both require oxygen to proceed.
both end with the electron transport chain.

Explanation:

Aerobic respiration and anaerobic respiration both start with glycolysis. Glycolysis is the breakdown of glucose into pyruvate. Aerobic respiration occurs in mitochondria and requires oxygen, ending with the electron transport chain. Anaerobic respiration does not occur in mitochondria and does not require oxygen.

Answer:

A. Both begin with glycolysis.
