Detailed explanation-1: -The process of breakdown of food in the cell with the release of energy is called cellular respiration. Cellular respiration takes place in the cells of all organisms. In the cell, the food (glucose) is broken down into carbon dioxide and water using oxygen.

Detailed explanation-2: -cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

Detailed explanation-3: -Respiration releases energy through the production of ATP. Respiration is a chemical reaction in which living cells release energy from glucose (food) by producing ATP. The ATP provides energy for cells. Respiration is an exothermic reaction.

Detailed explanation-4: -Respiration is the process by which cells release energy from nutrients. In most cases the food has already been broken down to glucose and it is the glucose that is worked on by the cells to produce energy.

Detailed explanation-5: -Glycolysis. Glycolysis is a metabolic pathway that occurs in the cytosol of the cell and splits glucose into two other molecules, called pyruvate. The free energy released in this process is used to form the high-energy compounds ATP AND NADH.
