Mitochondria convert the energy in the bonds of glucose and oxygen to readily available energy in the form of ATP (Adinoshin Tri Phosphate) with the help of oxygen. Mitochondria are often referred to as the powerhouse of cell.
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.
