NEETBotanyBiomolecules (B)
Read the following statements carefully: (A) Transferases catalyse the transfer of a group, including hydrogen, between a pair of substrates. (B) Lyases catalyse the removal of groups from substrates by mechanisms other than hydrolysis, leaving double bonds. (C) Hydrolases catalyse the hydrolysis of ester, ether, peptide and glycosidic bonds. (D) Ligases catalyse the linking together of two compounds, such as joining
Options
- AOnly one
- BOnly two
- COnly three
- DAll four
Correct answer
C. Only three
Step-by-step solution
Statement (A) is incorrect because transferases catalyse the transfer of a group (other than hydrogen) between a pair of substrates. The transfer of hydrogen is typically catalysed by oxidoreductases/dehydrogenases. Statement (B) is correct as lyases catalyse the removal of groups by mechanisms other than hydrolysis, leaving double bonds. Statement (C) is correct as hydrolases catalyse the hydrolysis of ester, ether, peptide, glycosidic, C - C , C -halide or P - N bonds. Statement (D) is correct as ligases catalyse
