Describe the importance of cofactors for enzyme efficient activity.

Text Solution

Verified by Experts

Many enzymes require non-protein components called cofactors for their efficient activity. Cofactors may vary from simple inorganic ions to complex organic molecules. They are of three types: Inorganic ions, Prosthetic groups and Coenzymes.

1. Inorganic ions: Help to increase the rate of reaction catalysed by enzymes. Eg: Salivary amylase activity is increased in the presence of chloride ions.
2. Prosthetic groups: Are organic molecules that assist in catalytic function of an enzyme. Flavin Adenine Dinucleotide (FAD) contains riboflavin (vit B2), the function of which is to accept hydrogen.
3. Coenzymes: Are organic compounds which act as cofactors but do not remain attached to the enzyme. The essential chemical components of many coenzymes are .vitamins. Eg. NAO, NADP, Coenzyme A, ATP.
