enzymes
Enzymes are proteins, composed of polypeptide chains and non-protein
groups. Their function is to help with the reactions of many cells and
molecules by serving as catalysts. A catalyst is a substance that allows the
activation energy required for a reaction by forming a temporary association
with the molecules that are reacting. During this process, the catalyst itself is
not permanently altered in the process, and so it can be used over and over
again. …showed first 75 words of 383 total…

the active site from binding to the proper substrate. An allosteric change
could be either a negative modulator or a positive effector. There’s also
cooperativity. This is the binding at an active site that makes the others more
reactive. An example to this is hemoglobin. Co-enzymes are also factors of
enzymes. These are heme-groups or prosthetic groups that bind to the
enzymes loosely as part of the reactions, such as vitamins.
