Do you know how to our body make energy? When we eat the food, I will digest and absorbed by cells. In the cell, cell turns food into useful energy, ATP. This process called cellular respiration, and I will explain about it. There are three steps of cellular respiration, glycolysis, pyruvate oxidation and citric acid cycle, and oxidative phosphorylation. First step is glycolysis which means “splitting sugars”. Glucose is a 6 carbon sugar; it divides into two molecules of a 3 carbon sugar called pyruvate by enzymes. In the process, 2 molecules of ATP, 2 molecules of NADH, and 2 pyruvates are produced. NADH is high energy electron carrying molecules, and it will make energy in oxidative phosphorylation step. Cellular respiration needs oxygen
