Question

which resource is needed for cellular respiration, but not fermentation?
glucose
water
oxygen
carbon dioxide

Explanation:

Cellular respiration is an aerobic process that requires oxygen. Fermentation is an anaerobic process that does not require oxygen. Both cellular respiration and fermentation use glucose. Water is a product of cellular respiration, not a required resource for the process itself. Carbon dioxide is a product of both cellular respiration (in the citric acid cycle) and some types of fermentation (such as alcoholic fermentation).

Answer:

C. Oxygen
