Breaking down food to release energy?
The process of breaking down food to create energy is called digestion. Digestion is necessary for other biological processes, such as movement and growth, to occur.
Not sure if that person's answer would answer your question but it sure as heck didn't answer mine... so I looked it up. The answer you might be looking for is binary fission. Not 100% sure though so don't be mad if i'm wrong. -_-
Breaking down food is usually called digestion, but this does not release its energy, it just makes the food molecules smaller and soluble so we can absorb them through the gut wall and into the bloodstream. The actual release of energy is respiration, which happens in the mitochondria of our cells.
