Which of the following molecular motors is associated with intermediate filaments?
a. kinesins
b. dyneins
c. myosins
d. none of the other answers
e. a, b and c

d. none of the other answers

Explanation:

Enzymes that turn chemical energy into mechanical work are molecular motors.

There are three main components of cytoskeleton including microtubules, actin filaments and Intermediate filaments. Only actin  filaments and microtubules carry the motor-driven transport on the cytoskeleton.

The most important feature of intermediate filaments is to provide the plasma membrane with mechanical support where it comes into contact with the extracellular matrix and other cells.

Unlike microtubules and microfilament , intermediate filaments are not involved in motility of the cells, hence do not associat with molecular motors.

Hence, the correct option is d.

1: the largest region of the brain is the:

  cerebrum

2. the term "psychology" literally means:

the process or procedure of the science or study of the mind.

3. the area of the brain responsible for respiration, heart rate, and smooth muscle control of our blood vessels is t

medulla oblongata

4. the structure that conducts nerve impulses to and from the brain and serves as a reflex center for some sensory information without input from the brain is the:

spinal cord

5. the three-layered membrane that covers the brain and spinal cord and literally means membrane is called the:

meninges

6. the cord-like (string-like) structures that carry bio-electrical impulses from one part of the body to another are called

nerves

7. a group of nerve cell bodies that are found outside of the spinal cord and brain are referred to as:

ganglions or ganglia (pl.) “literal meaning knot”

8. the term that means spinal cord inflammation is:

myel/itis
