Final answer:
Kinesin moves cargo vesicles towards the plus end (+end) of the microtubules, facilitating anterograde transport in cells, especially in neuron axons from the cell body to nerve endings.
Step-by-step explanation:
Kinesin is a motor protein that moves along microtubules, which are part of the cellular cytoskeleton. These proteins function as ATPases, using the free energy from ATP hydrolysis to generate mechanical force. Organelles and vesicles, like those containing neurotransmitters, are common cargo for these motor proteins. Kinesin specifically powers the anterograde transport, which means it moves cargo vesicles towards the plus end (+end) of the microtubules, away from the cell body to the nerve endings. In contrast, cytoplasmic dynein moves cargo along microtubules toward the minus end (-end), which typically is towards the cell body. This process ensures efficient transport and distribution of cellular components.
