Question

Are my answers correct? 53 54.Use the image to the right. The arrow indicates direction of the Action Potential Ca 2 53. A is a Synaptic Vesicle it A. Holds Neurotransmitters B. Holds Ca++ C. Is the powerhouse of the cell D. Carries Neurotransmitter to Cell Body 54. B shows the release of Neurotransmitter into the Synaptic Cleft. Because this is a Neuromuscular junction this Neurotransmitter wil1 induce in the Muscle Fiber A. Na++ influx into the cell Na++ outflux from the cell C.ATP production from glucose D. Muscular Dystrophy

Explanation / Answer

Yes A is synaptic vesicles that carries neurotransmitter to the cell membrane where it fuses with the membrane and release neurotransmitter into the synaptic cleft. This is how action potential give information to muscles to contract and do action. And cell body is axons top part. So ans is d.

When muscles receive neurotransmitter they need energy to contract i. E. ATP this atp comes from the break down of Glucose molecule into pyruvate. One atp is needed to attach one myosin filament with actin. So ans is c
