How do enzymes effect biochemical reactions?

Answer 1

Enzymes catalyze biochemical reactions by creating enough product that it eventually becomes an inhibitor to the enzyme and will essentially control the rate of reaction with the amount of product produced.

Answer 2

Enzymes catalyze biochemical reactions by lowering the activation energy required for the reaction to occur. They do this by binding to specific substrates and facilitating the formation of product molecules. Enzymes are not consumed in the reaction and can be used repeatedly.

Answer 3

Enzymes are (proteineous) bio-catalysts. They speed up reactions at normal temperatures and most of them are quite specific for one (or one group of) reaction(s).
