Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which process involves the release of energy from food substances in all living cells?
A
breathing
B
nutrition
C
respiration
D
digestion
Explanation: 

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: -The process where energy is released in cells is called cellular respiration. There are two types of cellular respiration: aerobic respiration and anaerobic respiration. Both types of cellular respiration use glucose to produce energy in the form of adenosine triphosphate (ATP).
