Question

Match the terms to these definitions
Cofactor, coenzyme, holoenzyme, apoenzyme, ligases, lyases, transferases, isozymes, zymogens, competitive inhibitor, non-competitive inhibitor, activation energy
..........enzymes which catalyse the linking together of compounds utilising the energy from ATP

Answer 1

The cofactor is a substance whose presence is essential for the activity of an enzyme.

The holoenzyme is an active compound which is formed by the combination of enzyme and coenzyme.

An apoenzyme is an inactive enzyme.

Ligase is an enzyme which brings ligation of DNA and another substrate. Lyases are the enzymes which catalyse the joining of specified molecules.

A transferase is a class of enzyme that intact the transfer of specific functional groups.

Isozymes are those enzymes which differ in from each other and occur in a different number.

Zymogens are the inactive compound which converts into an enzyme when activated by another enzyme.

A competitive inhibitor will block the enzymes active site.

A non-competitive inhibitor will bind the enzyme somewhere other than the active site.

The energy which is absorbed before stating a reaction is called activation energy.

Ligases are the enzymes which catalyze the linking together of compounds utilizing the energy from ATP.
