[DIAGRAM: A reaction scheme showing transfer of a functional group G from one substrate S-G to another substrate S#, yielding S and S#-G.] Name the class of enzyme that usually catalyze the following reaction: S - G + S# -> S + S# - G Where, G -> a group other than hydrogen; S -> a substrate; S# -> another substrate.

The answer appears as a continuous sentence in NCERT. This is that sentence.

How this line gives the answer

0, emb=1.0, combined=1.0). Verified: high — The NCERT span explicitly defines transferases as enzymes catalyzing the transfer of a group G (other than hydrogen) between substrates S and S', with the exact reaction S-G + S' → S + S'-G, which matches the question's reaction scheme and distinguishes it from other enzyme classes.

We did this for 1,565 questions.
