Acetylcholine (ACh) is the primary neurotransmitter responsible for muscle contraction. The binding of ACh to receptors on muscle cells activates a signal transduction pathway that causes the muscle to contract. Acetylcholinesterase, the digestive enzyme found on the membranes of muscle cells, is responsible for the breakdown of ACh over time, ending the activation of muscular contraction. Certain chemical compounds, such as sarin gas, act as high-affinity inhibitors of acetylcholinesterase. Which of the following describes the most likely effect that exposure to sarin would have on muscle cells? A B с D complete inhibition of muscle contraction slower transduction of the muscle contraction pathway decrease in the frequency of muscle contraction convulsions due to continuous muscle contraction
