Question

Formation of both peptide bonds and glycosidic bonds

• A. Involve addition of a phosphate group to the precursor molecules
• B. Would not require a catalyst in biological systems
• C. Involve removal of a water molecule
• D. Involve addition of carboxyl group

Answer 1

Answer: (C)

Involve removal of a water molecule

When there is formation of peptide or glycosidic bond, there is loss of one water molecule.

Phosphate group is not required in proteins and carbohydrates formation. In the formation of proteins, ribosomes acts as the catalyst in the biological system. No addition of carboxyl group is required.

Thus, the correct answer is option C.
