What happens to the oxygen released during photosynthesis ?

The correct option is A. The oxygen atoms diffuse through the atmosphere and are inhaled by animals.

Explanation:

Photosynthesis can be described as a process in which plants use the light from sun to convert carbon dioxide and water into glucose. Oxygen is made as a by-product of this reaction. This oxygen is released into the atmosphere by the plants through the mechanism of diffusion.

The oxygen released into the atmosphere is taken up by animals. Animals utilize this oxygen for the process of respiration.

The process of respiration and photosynthesis are opposite to each other.

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme
