calorie
The form of energy stored in food is called chemical energy. This energy is released when the bonds in food molecules are broken down during digestion.
The release of energy from food molecules in the absence of oxygen is called anaerobic respiration. When there is oxygen present it is called aerobic respiration.
fermentation
Respiration is the series of chemical reactions used to release energy stored in food molecules. it is also the process by which producers and consumers release stored energy from food molecules.
The process by which organisms break down macro molecules is called catabolism. Synthesizing small molecules and conserving energy is called anabolism. Anabolism and catabolism together is called metabolism.
The location of energy release from food molecules is in the mitochondria of the cell. The process in which energy is released from food molecules is known as cellular respiration.
The process that transforms energy in food molecules to usable energy is called cellular respiration. During cellular respiration, glucose molecules in food are broken down in cells to produce ATP (adenosine triphosphate), which is the form of energy that cells can readily use to power their functions.

mitochondria are the power house of the cell
This energy is derived from the chemical bond energy in food molecules, which thereby serve as fuel for cells. The first step is the enzymatic breakdown of food molecules in digestion, and the second step that converts glucose molecules is called glycolysis.
The organelle responsible for breaking down food into molecules that the cell can use for energy is the mitochondria. Through a process called cellular respiration, mitochondria convert glucose and other nutrients into a form of energy called ATP.
