Select the incorrect statement w.r.t. co-factors.
A
Prosthetic groups are organic compounds.
B
Association of co-enzyme with apoenzyme is transient.
C
NAD contains vitamin B₃.
D
Metal ions cannot act as co-factor.
Explanation
Both prosthetic groups and co-enzymes are organic compounds which act as co-factor but prosthetic groups are tightly bound with apoenzymes and association of co-enzyme is transient. The essential chemical component of many co-enzymes are vitamins. Metal ions can also act as co-factor. Zinc with carboxypeptidase is an example.
