Final answer:
Kinesin and dynein are the two types of motor proteins that facilitate cellular movement by transporting cargo along microtubule tracks using energy from ATP hydrolysis.
Step-by-step explanation:
The two types of motor proteins include kinesin and dynein. These proteins play a crucial role in cellular motility, as they can move cargo, such as organelles and vesicles, along microtubule tracks within the cell, utilizing the energy from ATP hydrolysis. Microtubules themselves are not motor proteins; they are composed of alpha-tubulin and beta-tubulin and serve as tracks for motor proteins. Similarly, actin is a protein that forms microfilaments, which work with the motor protein myosin, particularly in muscle cells, to facilitate cellular movement.
