During the transmission of signals across a neuromuscular junction, which of the following happens last? . a. acetylcholine binds to a receptor protein on the motor end plate.. b. sodium and potassium ion gates in the motor end plate open.. c. synaptic vesicles release acetylcholine molecules.. d. synaptic vesicles move toward the axon terminals..

During the transmission of signals across a neuromuscular junction, the one that happen last is : C. synaptic vesicles release acetylcholine molecules

The process was carried out by the motor neuron at the neuromuscular junction to change the permeability of the cell membranes

hope this helps

Answer - A

A neuromuscular junction is a synapse between a neuron and a muscle fibre and the binding of acetylcholine on a receptor protein on the motor end plate is the last step in the transmission of signals across a neuromuscular junction.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
