metabolism
The cellular process of breaking down food to release energy is called cellular respiration. During cellular respiration, glucose is broken down in the presence of oxygen to produce ATP, the cell's main energy source. The process occurs in the mitochondria of cells and involves several biochemical steps to extract energy from the food molecules.
When a mineral breaks down and releases energy, it is known as a chemical reaction or a chemical process. This process may involve the release of heat, light, or other forms of energy as bonds are broken and new substances are formed.
Bacteria helps you break down food along with your stomach acid. the process of respiration allows you to release energy. Resperation is the process in which food is broken down and energy is released.
the digestive system
Mitochondria.
Enzymes
Food needs to be combined with oxygen in a process called combustion to release the energy stored in it. This combustion process breaks down the food molecules, releasing energy that can be used by the body.
photosynthesis
The process is respiration (cellular respiration). It breaks down the compounds called carbohydrates to release the energy stored there (which almost always originally came from photosynthesis).
sugar
Mitochondria
Fermentation is a process that breaks down sugars into energy without using oxygen, while cellular respiration is a process that breaks down sugars with the use of oxygen to produce energy.
