What type of potential is generated in the post-synaptic neuron as a result of neurotransmitter binding to specific receptors?
Options
- AA new potential
- BAn electrical current
- CAn inhibitory potential
- DAn excitatory potential
Correct answer
D. An excitatory potential
Step-by-step solution
The action potential is generated in response to a stimulus and travels along the length of the axon, transmitting the nerve impulse. The rise in permeability to Na⁺ is short-lived and is followed by a rise in permeability to K⁺. K⁺ diffuses outside the membrane, restoring the resting potential of the membrane. The new potential developed in the post-synaptic neuron as a result of neurotransmitter binding to specific receptors may be either excitatory or inhibitory. Impulse travels faster in electrical synapse The
