Answer: Cellular respiration is a metabolic process that involves the oxidation of biological fuel (glucose) in presence of inorganic electron acceptor ( oxygen) in order to release large amount of energy in the form of ATP( adenosine triphosphate) that is upto 38 molecules.
CO₂ and H₂O are produced as waste products. The energy from ATP is utilized for various cellular activities.
The energy from glucose is changed to ATP through a series of metabolic reactions that occur in three phases that is glycolysis, kreb cycle, and electron transport chain.
