Adenosine Triphosphate. Adenosine triphosphate, or ATP, is the primary source of energy in both plant and animal cells. ATP is a nucleotide that is the basis for all cell reactions, including the reactionary process of converting food molecules into energy.Aug 7, 2017
For a chemical reaction to occur, activation energy is required. Using the activation energy, reactants form products by breaking bonds which require energy. This type of reaction is an endothermic reaction. When products are formed, bonds are formed back by releasing energy. This type of reaction is an exothermic reaction. When activation energy is used for a reaction, a catalyst is not required. Adding a catalyst to the reaction causes the rate of reaction to increase.
