At the optimum temperature the amylase will break down starch very quickly. At low ...

Enzymes bind both reactant molecules (called the substrate), tightly and specifically, at a site on the enzyme molecule called the active site (Figurebelow). By binding reactants at the active site, enzymes also position reactants correctly, so they do not have to overcome intermolecular forces that would otherwise push them apart.

Enzymes are biological catalysts that speed up reactions. The active site is where substrates bind to the enzyme. Induced fit occurs when the enzyme changes shape to better accommodate substrates, facilitating the reaction. Enzymes can be used multiple times and are affected by factors such as temperature and pH. Created by Sal Khan. Questions.24. 4. 2023 ...
