Cytoskeleton Chapter 16

What is A Actin?

• A microfilament have twisted double chain of actin subunits.
• A actin subunits.
• I don't know.
• Doesn't have a double chain.

What is A Myosin?

• An actin fiber.
• making less cell.
• Pulling stacks of actin fiber together and making less cell.
• Making things come together.

In the order of the lesson what are the three main type of fiber.

• microfilaments, microtubuies, and intermediate filaments
• intermediate filaments, microfilaments, and microtubuies
• microfilaments, intermediate filaments, and microtubuies
• microtubules, microfilaments, and intermediate filaments.

What is the Microtubules?

• the losses fibers
• the thickest fibers
• the tightest fibers
• the middle fibers
