Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
It forms bonds by addition of the water component.
A
hydrolases
B
helicase
C
ligase
D
isomerases
Explanation: 

Detailed explanation-1: -The hydrolysis involves several steps, of which the slowest is the formation of a covalent bond between the oxygen atom of the water molecule and the carbon atom of the ester.

Detailed explanation-2: -In fact, Hydrolysis can be the reverse of a condensation reaction in which two molecules join together into a larger one and eject a water molecule. Thus hydrolysis adds water to break down, whereas condensation builds up by removing water.

Detailed explanation-3: -Hydrolases – These catalyse splitting of larger molecules into smaller molecules by addition of water (hydrolysis) and breaking of bonds like ester, ether, peptide, glycosidic, C-C, C-halide, P-N, etc. which are formed by dehydration condensation.

Detailed explanation-4: -The reaction hydrolases do is hydrolysis. Hydrolysis is a chemical reaction in which water is used to break down a compound by inserting a water molecule across a bond. Was this answer helpful?
