Cellular respiration is a process by which cells harvest the energy stored in food.

Cellular Respiration and Fermentation Glycolysis: There are two important ways a cell can harvest energy from food: fermentation and cellular respiration. Both start with the same first step: the process of glycolysis which is the breakdown or splitting of glucose (6 carbons) into two 3-carbon molecules called pyruvic acid. The energy from other sugars, such as fructose, is also harvested using ...
