Question

Which of the following do not play a role in intracellular

movement?

a. microfilaments and intermediate filaments

b. microfilaments and microtubules

c. intermediate filaments and microtubules

d. only intermediate filaments

Short answer

only intermediate filaments does not have any role in intracellular movement.

Step-by-step solution

Explanation

Microfilament has myosin, a motor protein that helps in movement but intermediate filament does not have that ability. So, option a is wrong.

Microfilament has myosin and Microtubules has dynein which both are motor protein and help in cellular movement. Hence, option b is wrong as well.

Microtubules help in intracellular movement because of their flexibility and motor protein, but intermediate filaments do not. Option c is wrong too.

Option d is correct because only intermediate filament does not help in intracellular movement as they are rigid and help in adherence.

Conclusion

The only intermediate filament can not help in intracellular movement and helps in anchorage and adherence.
