Enzymes are proteins that speed up reactions by providing an additional energy source supplying additional molecules for the reaction removing inhibitors that slow down reactions lowering the amount of energy required

Lowering the energy required

Enzymes are biological catalyst or chemical reactants that can speed up rate of reaction between the substances without them being affected by it. They play a vital role in bodily functions like digestion. Enzymes and co-enzymes would often work together in order to create a fermentation process in the body

Enzymes are biological catalysts. Catalysts work by lowering the amount of energy required to set off a chemical reaction.
