Aerobic Respiration Produces Two Substances That are Used in Photosynthesis

Question

Aerobic respiration produces two substances that are used in photosynthesis.Which ones are these?  
A) Glucose and oxygen
B) Water and carbon dioxide
C) Citric acid and carbon dioxide
D) Starch and alcohol
E) Glucose and carbon dioxide

Accepted Answer

Aerobic respiration produces water and carbon dioxide, which are both used in photosynthesis as reactants. Glucose is produced during photosynthesis, not respiration. Citric acid is a product of the citric acid cycle in respiration, but it is not used in photosynthesis. Starch and alcohol are not produced in aerobic respiration.
