Answer:
B. Synaptic vesicle—neurotransmitter—ion channels—end plate potential
Explanation:
When an impulse reaches the synaptic knob, it stimulates the vesicles to move towards the pre-synaptic membrane releasing the acetylcholine(neurotransmitter). This transmitter substance makes the membrane permeable. The transmitter substance then diffuses across the synaptic cleft to the post-synaptic membrane which then becomes depolarised. Sodium ions from cleft then flow through the post-synaptic membrane into the post-synaptic knob causing an action potential at this point. This action potential is then transmitted as a nerve impulse along the neurone. End-plate potential is a change in electrical potential that is chemically induced at the motor neurone leading to muscle contraction because a nerve impulse has reached the nerve endings.
Before you faint, you feel dizzy. The dizziness is from the light headedness.
All the energy (Kcal) on the earth is from the sun. plants absorb the energy then an animal/organism will consume it then the animal will use 10% of the energy then some will eat that animal and process will continue but the less the energy there is the more the next animal will eat
