Answer;
-This suggests that succinylcholine must be a competitive inhibitor of acetylcholine
Explanation;
-Enzyme inhibitors are molecules that interact in some way with the enzyme to prevent it from working in the normal manner. Enzyme inhibitors include; nonspecific, irreversible, reversible - competitive and noncompetitive.
-A competitive inhibitor is any compound which closely resembles the chemical structure and molecular geometry of the substrate. In this case Succinylcholine resembles acetycholine. Â The inhibitor competes for the same active site as the substrate molecule.
-Competitive inhibition occurs when a molecule mimics the substrate. Succinylcholine is neuromuscular blocking agent that is competitive inhibitor of acetylcholine at neuromuscular junction  and results in muscle paralysis.
