Chapter 3.5, Problem 1QC

Summary Introduction

To review:

Match the terms microtubules, intermediate filaments, or actin filaments with the most closely related descriptions given below:

(a) Thinnest cytoskeletal filaments; are associated with motor protein myosin.

(b) Consists of proteins twisted together in a rope-like form

(c) Allow certain cells to “crawl” and change the shape and the size of the cell

(d) Consists of protein subunits surrounding a hollow core

(e) Help a cell to resist mechanical stress

(f) Grow from the cell’s centrosome

Introduction:

The microtubules, intermediate filaments, and the actin filaments belong to the cytoskeleton of the cell. The cytoskeleton is composed of the different types of the protein filaments, which are organized according to their functions.
