Free Conjugated Molecules MCQs with Answers
34 Conjugated Molecules MCQs from Biology, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Conjugated molecules contain a non-protein component attached to a protein portion, giving the molecule properties that a simple protein lacks. The content includes glycoproteins, lipoproteins, phosphoproteins, nucleoproteins, chromoproteins and metalloproteins, with attention to their prosthetic groups and roles in transport, protection, catalysis and cellular structure.

Explanation: Any protein molecule with a carbohydrate attached is known as a glycoprotein.
Correct answer: Glycoproteins- A. They are conjugated molecules of carbohydrates
- B. Both have role in the extracellular matrix of animals and bacterial cell wall
- C. They are components of biological membranes.
- D. Both are produced and secreted by endoplasmic reticulum
Explanation: D is correct because glycoprotein and glycolipids are secreted by golgi apparatus .It also modifies these conjugated molecules.
Correct answer: Both are produced and secreted by endoplasmic reticulum- A. They are conjugated molecules of carbohydrates
- B. Both have role in the extracellular matrix of animals and bacterial cell wall
- C. They are components of biological membranes.
- D. Both are produced and screted by endoplasmic reticulum
