Certain natural plant poisons and animal venoms contain substances that inhibit the function of acetylcholinesterase. If a person is poisoned by one of these substances, which of the following will be the cause of their symptoms?
A)Their muscles won't be able to contract because no acetylcholine will be released from the neuronal membrane.
B)Their muscles will be in a constant state of contraction because acetylcholine won't be broken down and cleared from the neuromuscular junction.
C)Their muscles won't be able to contract because acetylcholine will be attacked and degraded immediately after release from the neuron.
D)Their muscles won't be able to contract because acetylcholine won't be properly synthesized by acetylcholinesterase.
