Question

Which process has oxygen as a product and which has oxygen as a reactant?

A. Photosynthesis - Oxygen as a product.
B. Cellular respiration - Oxygen as a reactant.
C. Fermentation - Oxygen as a product.
D. Glycolysis - Oxygen as a reactant.

Answer 1

Photosynthesis produces oxygen as a product, while cellular respiration uses oxygen as a reactant.

Step-by-step explanation:

Photosynthesis is the process that has oxygen as a product. During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen. The equation for photosynthesis is 6CO2 + 6H2O + Energy -> C6H12O6 + 6O2.

On the other hand, cellular respiration is the process that has oxygen as a reactant. During cellular respiration, cells break down glucose in the presence of oxygen and release carbon dioxide, water, and energy. The equation for cellular respiration is C6H12O6 + 6O2 -> 6CO2 + 6H2O + Energy.
