    Acetylcholine helps in:

    A)  synaptic transmission

    B)  membrane permeability

    C)  synaptic delay

    D)  none of the above

    Correct Answer: A

    Solution :

    When the action potential reaches the nerve terminal it causes the release of a chemical neurotransmitter (amino acids, glutamate, glycine, acetylcholine etc.) from the synapric vesicles into the synaptic cleft by exocytosis of \[C{{a}^{2+}}\] dependent and interact with receptors on the surface of post-synaptic cell, causing a signal to be transduced in that cell. Membranes are responsible for taking in and concentrating raw materials used for cellular chemical activities along with these and removing waste products also from the cell.
