Assertion: Arachidic acid is an unsaturated fatty acid.
Reason: There are one or more double bonds between carbon atoms in unsaturated fatty acids.

Assertion: A coenzymes or metal ions that is very tightly bound to enzyme protein is called prosthetic group.
Reason: A complete, catalytically active enzyme together with its bound prosthetic group is called apoenzyme.
