Answer 2

Hii There!!

We do breathing to intake oxygen and to release energy in the form of ATP for cellular respiration.

During this process, glucose is broken into pyruvate and it furthur divides to form Carbondioxide , water along with the release of energy.
This process takes place in mitochondria.
