Question

Which of the following statements about the cytoskeleton is true?

A. Chemicals that block the assembly of the cytoskeleton would cause little effect on the cell's response to external signals and stimuli.
B. The dynamic aspect of cytoskeletal function is made possible by the assembly and disassembly of a large variety of proteins into complex aggregates.
C. Movement of cilia and flagella is the result of motor proteins causing microtubules to move relative to each other.
D. Transport vesicles among the membranes of the endomembrane system produce the cytoskeleton.
E. Microfilaments are structurally rigid and resist compression, whereas microtubules resist tension (stretching).

Answer 1

The dynamic aspect of cytoskeletal function is made possible by the assembly and disassembly of a large variety of proteins into complex aggregates.

Step-by-step explanation:

The statement that is true about the cytoskeleton is:
B. The dynamic aspect of cytoskeletal function is made possible by the assembly and disassembly of a large variety of proteins into complex aggregates.

The cytoskeleton is composed of three types of protein elements: microfilaments, intermediate filaments, and microtubules. While intermediate filaments serve a mainly structural role, microfilaments and microtubules have dual functions of maintaining cell shape and enabling cell motility. The assembly and disassembly of these proteins allow for the dynamicity of the cytoskeleton, enabling cells to change shape and perform various functions.
