Just like in plants, photosynthesis makes food and energy for in
the form of glucose, animal cells like we have in our bodies, need to make ATP (Adenosine triphosphate) for energy.The first
process of cellular respiration is called aerobic respiration. This process will happen when oxygen is present. There is also
anaerobic respiration, which will happen in the absense of oxygen.
Aerobic respiration can be broken down into four phases. These are
Glycolysis, Transition Reactions, Kreb's Cycle and Electron Transport Chain.
