Enzymes are that speed up chemical reactions in . At low temperatures, small increases in temperature increase the and energy of collisions between an enzyme and other molecules, so the rate of increases. Enzymes have a small part called the site where certain molecules can bind to the , and the chemical reaction takes place. Only molecules with the correct can fit into the active site and that this is described as the lock and model. The shape of the active site is changed by the enzyme above a certain temperature. Then the molecules can no longer and the reaction cannot happen.
