Answer
Alidcarb does not permanently block the active site, as it is a reversible inhibitor.
Step 2
B. acts by strongly binding to the active site of acetylcholinesterase.

Answer
While Alidcarb does bind to the enzyme, it is not necessarily by strong binding, making it an incorrect description.
Step 3
C. increases the rate at which acetylcholine is broken down into acetate and choline.

Answer
Alidcarb does not increase this rate; it inhibits the enzyme, leading to less breakdown.
Step 4
D. reduces acetylcholinesterase activity by reducing the number of active sites for acetylcholine to bind to.
