The video explains the role of motor proteins, particularly kinesin, in cellular functions. Motor proteins transport materials within cells using the microtubule cytoskeleton. Kinesin, a type of motor protein, moves along microtubules using ATP for energy. It plays a crucial role in nerve cells by transporting neurotransmitters. Motor proteins also assist in cell division by moving chromosomes. The video highlights the importance of these proteins in maintaining cellular functions.

What is the primary role of motor proteins within cells?

• To form the structure of the cell

• To carry cellular material to where it is needed

• To protect the cell from external damage

• To provide energy for cellular processes

What is the microtubule cytoskeleton primarily made of?

• Actin

• Myosin

• Keratin

• Tubulin

How does kinesin move along the microtubule?

• By jumping

• By sliding

• By rolling

• By walking

What is the role of ATP in the movement of kinesin?

• It provides the energy needed for movement

• It signals the direction of movement

• It acts as a lubricant

• It forms the structure of kinesin

How do motor proteins assist in cell division?

• By providing energy for cell division

• By rolling microtubules beneath them

• By signaling the start of division

• By forming new cells
