Energy that is required, transformed and stored in mammalian cells is usually in the form of ATP (adenosine triphosphate)4. Energy is released when the molecule is split from ATP to ADP (adenosine diphosphate). This is shown in the following reaction ATP ↔ ADP + Pi + energy for use4. ATP is formed from the breakdown of glucose, which is also seen in the equation C6H12O6 +O2 ↔ CO2 +H2O +36-38 ATP4. As seen in the equation 36-38 molecules are made per one molecule of glucose. The process of this equation from glucose to ATP has three parts glycolysis, Krebs cycle and electron transport chain (oxidation phosphorylation), which are also known as cellular respiration4.

Nerve cells communicate with their target cells as they are stimulated by the depolarization of the membrane, which are action potentials. Ions move down the axon of the membrane until they reach the axon terminal2. The synapse is the space between the axon terminal and its target
