Well there are 'generally' two types of enzymes: What they have in common is that they are all catalysts and so speed up the rate of a chemical reaction. They do so by lowering the activation energy, which is the minimum amount of energy required for a reaction to take place.eport Abuse. Enzyme is a catalyst (a chemical agent that speeds up a reaction). every chemical reactions involve bond breaking and forming. Changing one molecule to another involve contorting the starting molecule to an unstable stage (transition stage) before the actual reaction begin.
