BIOCATALYSIS
Enzyme
DEFINITION
A macromoleclue made up of protein that acts as s biological catalyst that speed up the rate of chemical reaction by lowering activation energy.
PROPERTIES
●All are globular proteins.
●Act as biological catalyst to increase the rate of biochemical reactions.
●Do not change structurally and chemically after a reaction/reusable.
●Highly specific for a particular subsrate in a reaction (each enzyme acts only on a specific substrate).
●Required in small amount.
●Lower the activation energy of a reaction by bringing the substrates into contact with one another.
●May catalyse reversible or irreversible reactions.
●Their activities are affected by pH, temperature, substrate concentration and enzyme concentration.
●Their activities is maximum at optimum temperature/pH.
●Can be denatured at extreme temperature or pH.
●Enzyme possess active sites where the substrate
molecules bind to for a reaction to take place.
●Does not alter the nature of the end product of the reaction.

COFACTOR
DEFINITION
Non-protein substance (organic/ in organic) essential for some enzymes to function efficiently.
-
Inhibitor
DEFINITION
A substance that interacts with the enzyme to prevent it from working in the normal manner, hence stopping or slowling a specific enzymatic reaction.
