What do cellular respiration and fermentation have in common?

A. they both occur in the mitochondria

B. they both harvest energy from sugars

C. they both require oxygen to occur

D. they both end up with pyruvic acid

The answer is letter B, They both harvest energy from sugars.

Only cellular respiration occur in the mitochondria and Fermentation does not require oxygen to occur since it is an anaerobic process. Lastly, pyruvic acid (pyruvate) enters either in the reductive pathways (fermentation) or oxidative pathway (respiration) and not on both pathways. - ahnnahly
