Enzymes that catalyse the transfer of molecules except H, O and electron are called as
Options
- ALigases
- BIsomerases
- CLyases
- DTransferases
Correct answer
D. Transferases
Step-by-step solution
Enzymes are proteinaceous compounds that accelerate a chemical reaction without changing its direction. Based on types of reaction, they catalyze the enzymes are of the following six types:
(i) Oxidoreductase-transfer of H and O atoms or electrons from one substance to another, e.g., Dehydrogenase, oxidase, catalase.
(ii) Transferases-transfer of a functional group from one substance, e.g., Phosphorylase, kinase.
(iii) Hydrolases-hydrolysis of the substrate e.g., Lipase, amylase, peptidase, protease, etc.
(iv) Lyases-splitting of C-C, C-O, C-N, C-H and other similar bonds. e.g., Decarboxylase, fumarase, aldolase.
(v) Isomerases-change of a substrate into a related form by intramolecular rearrangement, e.g., Phosphohexo-isomerase.
(vi) Ligases (synthetases)-joining of two molecules by forming new bonds with the simultaneous breakdown of ATP, e.g., Acyl Co-A synthase, pyruvate carboxylase.
