Question

What does ‘Z’ represent in the reaction?

Acetyl – D – carnitine + water \(_{\overrightarrow{Acetylcholine \,esterase}}\) Z + acetic acid

(a) D – carnitine

(b) Choline

(c) Hydroquinone

(d) L -carnitine

Answer 1

Right option is (a) D – carnitine

The best I can explain: In the above reaction, ‘Z’ represents D – carnitine which is produced by the action of acetylcholine esterase on acetyl – D – carnitine. L – carnitine cannot be produced as acetylcholine esterase is specific in action on acetyl – D – carnitine, rather than acetyl – L – carnitine. Choline is produced by the action of acetylcholine esterase on acetylcholine. Hydroquinone is produced when glucose oxidase acts on glucose and benzoquinone, rather than oxygen as the oxidant.
