Question

1. botulism is a serious form of food poisoning. it results when a substance called botulinus toxin, produced by bacteria, prevents the release of acetylcholine from motor nerve fibres. the effect is a. contraction of all skeletal muscles, resulting in paralysis b. the inability of atp to be released c. a decrease in ph due to buildup of lactic acid d. the failure of muscles to be stimulated hint: understand synapse structure and function in detail. use the (sr). you may think this question is easy now; however, by the time the final comes, will you still remember? this question presents two opposites; will the muscles not be stimulated and have no contractions or will they be stimulated and have continuous contraction? finding the one logic word will help you immensely.

Explanation:

Acetylcholine is a neurotransmitter that transmits signals from motor - nerve fibers to muscles, causing muscle stimulation and contraction. Botulinus toxin blocking acetylcholine release means muscles cannot receive the stimulation signal, leading to muscle failure to be stimulated.

Answer:

D. the failure of muscles to be stimulated
