Cellular respiration is defined as the process by which a. energy is released from molecules and is transferred to other molecules b. cells breathe, or take in o2 and give off co2 c. cells produce energy from o2 and absorb heat. d. energy is absorbed from glucose and is transferred to co2

Option A, Energy is released from molecules and is transferred to other molecules

Explanation:

In a cellular respiration, oxygen is taken in to  break down glucose (carbohydrate) to release carbon dioxide, water and energy molecules.

The chemical equation of a cellular respiration is as follows -

The energy contained in glucose molecule is converted into another energy molecule (ATP) with the help of oxygen.

Hence, option A is correct.

It's called Lipase, the enzyme.
