Question

Ligases is a class of enzymes responsible for catalysing the linking together of two compounds.Which of the following bonds is not catalysed by it?

• A. C-C
• B. P-O
• C. C-O
• D. C-N

Answer 1

The Correct Option is A

Ligases facilitate the creation of bonds connecting carbon to other elements such as oxygen, nitrogen, sulfur, and phosphorus (C-O, C-N, C-S, C-P). They do not directly catalyze the formation of C-C bonds. While certain ligase-mediated reactions can indirectly result in C-C bond formation in subsequent stages, ligases do not primarily join two carbon atoms directly.
