Transmission Of Nerve Impulse

The concentration of potassium ions inside a biological cell is at least 20 times higher than outside. The resulting potential difference across the cell is important in several processes such as transmission of nerve impulses and maintaining the ion balance. A simplel model for a concentration cell involving a metal M is M(s)|M^(o+)(aq,0.05 molar )||M^(o+)(aq,1 molar )|M(s) For the abov electrolytic cell, the magnitude of the cell potential is |E_(cell)|=70mV. For the above cell

A list of events occurring in the transmission of nerve impulse across the synapse is given below in a random order (i)Opening of specific ion channels allows the entry of ions, a new action potential is generated in the post-synaptic neuron. (ii)Neurotransmitter binds to the receptor on post synaptic membrane. (iii)Synaptic vesicle fuses with pre-synaptic membrane, neurotransmitter release into synaptic cleft. (iv)Depolarisation of pre-synaptic membrane. (v)Arrival of action potential at axon terminal. Which of the following options represents these events in a correct order ?

The concentration of potassium ions inside a biological cell is at least twenty times higher than the outside. The resulting potential difference across the cell is important in several processes such as transmission of nerve impulses and maintaining the ion balance. A simple mode for such a concentration cell involving a metal M is : M_((s))|M_((aq.))^(@) 0.05"molar"||M_((aq.))^(@) 1"molar"|M_((s)) For the above electrolytic cell the magnitude of the cell potential |E_(cell) | = 70mV For the above cell :
