The neurotransmitters binds to their specific receptors. This binding ____ ion channels allowing the ____of ions which can generate a new potential.
1 Opens, exit
2 Opens, entry
3 Closes, entry
4 Closes, exit
Explanation:
The neurotransmitters binds to their specific receptors, present on the post-synaptic membrane. This binding opens ion channels allowing the entry of ions which can generate a new potential in the post-synaptic neuron.
1 Electrical current can flow directly from one neuron into the other across the electrical synapse.
2 Chemical synapses use neurotransmitters
3 Impulse transmission across a chemical synapse is always faster than that across an electrical synapse.
4 The membranes of presynaptic and postsynaptic neurons are in close proximity in an electrical synapse.
Explanation:
Impulse transmission across an electrical synapse is always faster than across chemical synapse.

Alzheimer's disease in humans is associated with the deficiency of
1 Glutamic acid
2 Acetycholine
3 Gamma aminobutyric acid (GABA)
4 Dopamine
Explanation:
The pathogenesis of Alzheimer's disease(AD) has been linked to a deficiency in the brain neurotransmitter acetylcholine.

Which of the following regarding to nerve activity is true
1 The synaptic cleft does not prevent direct propagation of action potential from presynaptic neuron to post synaptic cell
2 Information occurs when the synaptic cleft is transmitted by means of a chemical neurotransmitter from small vesicle
3 Combination of neurotransmitter with receptor site changes membrane potential without changing membrane permeability
4 All are correct
Explanation:
Synaptic cleft is the gap between presynaptic neuron and post- synaptic neuron. During chemical synapse, membrane of pre-synaptic neuron and post-synaptic neuron is separated by a fluid - filled space called Synaptic Cleft.Synaptic cleft will allow propagation of action potential from presynaptic neuron to post synaptic neuron. Neurotransmitter binds to specific receptor on post synaptic membrane which leads to opening of ion channels which will allow entry of ions and generates a new electrical potential. Neurotransmitter acts by changing membrane permeability.
