What are co factors and co enzymes?

What are co factors and co enzymes?

Coenzymes are small, non-protein organic molecules that carry chemical groups between enzymes (e.g. NAD and FAD). Forms easily removed loose bonds. Cofactor is a non-protein chemical compound that tightly and loosely binds with an enzyme or other protein molecules.

What do Apoenzymes do?

Apoenzyme is the protein part of an enzyme. The non-protein part cofactor together with the protein part apoenzyme forms a holoenzyme. Apoenzymes are important for enzymatic activity since they are responsible for the specificity of enzymes to their substrates.

What is the difference between apoenzyme and coenzyme?

1. Coenzyme is the non-protein organic group which gets attached to the apoenzyme to form holoenzyme or conjugate enzyme. 2. It is small in size.

How Apoenzymes are formed?

Apoenzyme- An enzyme that requires a cofactor but does not have one bound. An apoenzyme is an inactive enzyme, activation of the enzyme occurs upon binding of an organic or inorganic cofactor. Holoenzyme- An apoenzyme together with its cofactor. A holoenzyme is complete and catalytically active.

What is apoenzyme and give example?

Apoenzyme or apoprotein is an enzymatically inactive protein part of an enzyme, which requires a cofactor for its activity. Apart from catalytic RNA, most of the enzymes are proteins. Not all the enzymes require a cofactor. Enzymes that do not require any cofactor are known as simple enzymes, e.g. pepsin, trypsin, etc.

Which vitamin is a cofactor?

Vitamins can serve as precursors to many organic cofactors (e.g., vitamins B1, B2, B6, B12, niacin, folic acid) or as coenzymes themselves (e.g., vitamin C)….Vitamins and derivatives.
