Question

An example of conjugated protein is

• A. Haemoglobin/Flavoprotein
• B. Globulin
• C. Albumin
• D. Peptone

Answer 1

Answer: (A)

Haemoglobin/Flavoprotein

Conjugated proteins are those which has a conjugated group or prosthetic group attached to it. Nucleoprotein has nucleic acid attached as prosthetic group. Lipoprotein has lipids and glycoprotein has glucose as prosthetic group. Haemoglobin has non-protein prosthetic heme group. A heme group consists of an iron (Fe) ion (charged atom) held in a heterocyclic ring, known as a porphyrin. It is a respiratory pigment present in the blood. Flavoproteins has flavoprotein as prosthetic group.

So, the correct answer is option A.
