The primary food molecules broken down for cellular energy are carbohydrates, fats, and proteins. Carbohydrates are converted into glucose, which can be used in cellular respiration to produce ATP. Fats are broken down into fatty acids and glycerol, while proteins are degraded into amino acids; both can be utilized for energy or converted into glucose or other metabolites. This metabolic process allows cells to generate the energy necessary for various functions.
chemical digestion or simply digestion
The energy released from food molecules is derived primarily from the breakdown of macronutrients like carbohydrates, fats, and proteins through cellular respiration. This process occurs in the mitochondria of the cell, where molecules such as glucose are metabolized to produce ATP, the cell's primary energy currency.
The breakdown of food into molecules small enough to enter the bloodstream is primarily accomplished by the process of digestion. This involves mechanical and chemical breakdown of food in the mouth, stomach, and intestines, with the help of enzymes, to break down macromolecules into smaller molecules that can be absorbed by the body.
the breakdown of food molecules
The process that breaks down food molecules and releases energy is called cellular respiration. This process occurs in the cells of organisms and produces ATP (adenosine triphosphate), the energy currency of the cell, through the breakdown of glucose and other molecules in the presence of oxygen.

Digestion is the breakdown of large food molecules into small, water-soluble food molecules that can be absorbed.
Mitochondria.
Digestion of the food particle occurs in a vesicle enclosed by a membrane that separates the digestion from the cytoplasm
The breakdown of molecules to release energy occurs in the mitochondria of a cell through a process called cellular respiration. This process involves the breakdown of glucose to produce ATP, the cell's main energy source, as well as carbon dioxide and water as byproducts.
Enzymes are the molecules responsible for catalyzing biochemical reactions, including the breakdown of food molecules. They act as biological catalysts by lowering the activation energy required for these reactions to occur.
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.
