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.

The answer to your question is Both begin with glycolysis. Aerobic respiration is the process of producing cellular energy involving oxygen. The first step in is glycolysis, the second is the citric acid cycle and the third is the electron transport system. Anaerobic respiration is a type of respiration that does not use oxygen. as Aerobic respiration, it starts with glycolysis.
