Detailed explanation-1: -Food contains oxygen which cells convert into energy.
Detailed explanation-2: -ATP is the main source of energy for most cellular processes. The building blocks of ATP are carbon, nitrogen, hydrogen, oxygen, and phosphorus. Because of the presence of unstable, high-energy bonds in ATP, it is readily hydrolyzed in reactions to release a large amount of energy.
Detailed explanation-3: -Summary. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
Detailed explanation-4: -The main function of cellular respiration is to synthesize biochemical energy. Cellular respiration is essential to both eukaryotic and prokaryotic cells because this biochemical energy is produced to fuel many metabolic processes, such as biosynthesis, locomotion, and transportation of molecules across membranes.
Detailed explanation-5: -Cells need a source of energy, they get this energy by breaking down food molecules to release, the stored chemical energy. This process is called ‘cellular respiration’.
