What happens to a substance when it becomes oxidized reduced

Binding of a regulator to the allosteric site of an enzyme changes its structure, making it more or less active. The molecules that bind cellular respiration enzymes act as signals, giving the enzyme information about the cell's energy state. ATP, ADP, and NADH are examples of molecules that regulate cellular respiration enzymes.
