Final answer:
Dynein and kinesin motor proteins are responsible for moving organelles and large molecules along the cytoskeleton in a cell. They use ATP hydrolysis to power their movement, with dynein moving cargo towards the center of the cell and kinesin moving cargo towards the periphery.
Step-by-step explanation:
The motor proteins that move organelles and large molecules along the cytoskeleton in a cell are dynein and kinesin.
These motor proteins are ATPases, which means they use the energy from ATP hydrolysis to power their movement.
Dynein is responsible for moving cargo towards the center of the cell, while kinesin moves cargo towards the periphery of the cell.
For example, secretory vesicles containing proteins or neurotransmitters can be carried by these motor proteins along microtubule tracks, allowing them to be released at the plasma membrane.
