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.
Just like architectural plans are blueprints on how the Megalopolis factory should be built, so is the DNA on how the cell should be built. They all store information. The plans have, for example, the number of rooms and dimension of the factory, while the DNA has genes that code for proteins (the actual building block for the cells).
