A
True
B
False
Verified step by step guidance1
Understand the role of kinesins: Kinesins are motor proteins that transport cellular cargo along microtubules. They are crucial for intracellular transport, especially in neurons.
Identify the direction of movement: Kinesins typically move towards the plus end of microtubules, which is usually oriented away from the cell body towards the periphery of the cell.
Consider the context of neuronal cells: In neurons, the cell body is the central part, and kinesins transport molecules towards the axon terminal, which is away from the cell body.
Relate the movement to cellular processes: This movement is essential for processes such as axonal transport, where materials are moved from the cell body to the synapse.
Conclude based on the information: Given the typical direction of kinesin movement, it is correct to say that kinesins move molecules away from the cell body.
