Explain the role of microtubules and motors in the movement of chromosomes during cell division.

Microtubules and motors work together to pull chromosomes during cell division. Motors such as kinesin and dynein travel along microtubules, utilizing ATP hydrolysis to move the chromosomes to their proper locations.

How does myosin contribute to muscle movement?

Myosin, a motor protein, binds to actin and uses ATP hydrolysis to generate force, contributing to muscle movement. When myosin pushes actin, it generates the force necessary for muscle contraction.

What are some of the components that make up more complex machines in cells?

Conformational changes in single proteins, cooperativity among proteins, filaments like microtubules and actin, and molecular motors such as kinesin, dynein, and myosin are some of the components that make up more complex machines in cells.
