5. A rare human disease involving the neuromuscular junction is the result of destruction of the voltage-gated calcium channels in the motor nerve terminal. How would this affect the
neuromuscular junction?
A. there would be a decrease in the re-uptake of calcium into the sarcoplasmic reticulum
B, acetylcholine would not be released from the nerve terminal
C. acetylcholine would be broken down more rapidly at the neuromuscular junction
D. acetylcholine receptors at the motor end plate would depolarize the sarcolemma
E, calcium concentration in the motor nerve terminal would increase
