Which one of the following statement is correct with reference to enzymes?
1 Apoenzyme \(=\) Holoenzyme + Coenzyme
2 Holoenzyme = Apoenzyme + Coenzyme
3 Coenzyme \(=\) Apoenzyme + Holoenzyme
4 Holoenzyme \(=\) Coenzyme + Cofactor
Explanation:
Exp: B Holoenzyme or conjugate enzymes consist of a protein as well as non protein part essential for the activity. - The protein part of the holoenzyme is known as apoenzyme which is inactive. - The non-protein part is called a coenzyme and is necessary for the catalytic function of the enzymes. So, holoenzyme is an active enzyme-cofactor complex i.e. an apoenzyme attached to a coenzyme. - Co-enzymes are tightly bound to the enzyme they are referred to as a prosthetic group.

Which of the following is not correctly matched for the organism and its cell wall degrading enzyme?
1 Fungi-Chitinase
2 Bacteria-Lysozyme
3 Plant cells-Cellulase
4 Algae-Methylase
Explanation:
Exp: D Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break other down. All living things have enzymes. Our bodies naturally produce enzymes.

Jacob and Monod named some enzymes as allosteric whose activity is regulated by
1 end product
2 substrate
3 by product
4 coenzyme
Explanation:
Exp: A Jacob and Monod named some enzymes as allosteric whose activity is regulated by end product. Allosteric enzyme have one or more allosteric sites. The term allosteric has been introduced by Jacob and Monod to denote an enzyme site different from the active site. These enzyme have one or more allosteric site that are binding site different from enzyme active site.
