Answer:
Intracellular transport is taking place with the help of microfilaments and microtubules. The plays the role of a highway for motor proteins such as dynein, kinesin, and myosin, which acts as the car of this highway that helps in transport.
Motor proteins help in changing the ATP to ADP by binding to it and attach or detach to the other parts of the cytoskeleton for transporting the vesicles as these proteins move.
Kinesin and dynein both are microtubule motor proteins. Kinesin transports full vesicles away from the nucleus, Dynein transports empty vesicles back towards the nucleus and myosin is a microfilament motor protein that transports both vesicles along microfilament.

The movement disorder is the restless legs syndrome. <span>This is a confusion that makes a compelling impulse move one's legs. There is frequently a repulsive inclination in the legs that enhance fairly with moving them. Every so often the arms may likewise be influenced. The emotions, by and large, happen when very still and in this way can make it difficult to rest.</span>
The question is incomplete as it does not have the options which are:
A. endocytosis
B. active transport
C. facilitated diffusion
D. infusion
E. osmosis
Answer:
B. active transport
Explanation:
The neuron cell involves the influx and efflux of the sodium and potassium ions. These ions move through membrane proteins by facilitated diffusion and active transport.
The active transport allows the movement of ions against the concentration gradient that is even if the concentration of ions is higher.
In the given question, although the potassium ions are higher in the cytoplasm of the neuron, the potassium ions can enter the cell through active transport.
Thus, active transport is correct.
