WebEnzymes that display this behavior can often be described by an equation relating substrate concentration, initial velocity, K_m K m, and V_ {max} V max, known as the Michaelis-Menten equation. Enzymes whose kinetics obey this equation are called Michaelis-Menten enzymes.

WebEnzymes are biological catalysts that speed up the chemical reactions which go on in the cells in all living things. What are enzymes? No. Enzymes are unchanged and can be reused. Are enzymes themselves changed during the reaction? Catalysts lower the activation energy needed for a reaction to occur, so a reaction can happen much more easily.

They are made inside cells. Most of them work inside the cell, but some (e.g. digestive enzymes) work outside the cell. Enzymes are biological catalysts. A catalyst speeds up a chemical reaction.
