Question

Name the class of enzyme that usually catalyzes the following reaction: \[ S - G + S^{\prime} \rightarrow S + S^{\prime} - G \] Where \( G \) represents a group other than hydrogen, \( S \) is a substrate, and \( S^{\prime} \) is another substrate.

• A. Lyase
• B. Transferase
• C. Ligase
• D. Hydrolase

Hint:

Lyases are enzymes that catalyze the addition or removal of groups to or from substrates without using water. Understanding the different types of enzymes helps to classify reactions correctly.

Answer 1

The Correct Option is A

The reaction described in the question involves the breaking or forming of bonds between substrates, often catalyzed by lyases. Lyases are enzymes that catalyze the addition or removal of groups to/from substrates, without using water (which would be the case in hydrolases). Thus, the correct enzyme class for this reaction is Lyase.
