Cellular respiration : aerobic :: fermentation : anaerobic
The main function of the mitochondria is respiration in the cell. To produce energy from broken down organic molecules. (i.e. carbohydrates.)
Our food is our energy. When we eat food, we need to digest it and the eaten food, once digested, serves as our energy that we use up for daily needs. If we eat too much food, it will be store and we will become overweight over time.
