Question

question 1
which of the following can assemble into cytoskeletal fiber
tubulin
actin
dynein
question 2
a motor protein:
uses atp to move
uses passive diffusion to move
question 3
an organelle being transported along a microtubule toward the plasma toward the:

Explanation:

Question 1:

Actin and dynein can assemble into cytoskeletal fibers. Actin forms microfilaments, and dynein is a motor - protein associated with microtubules which are part of the cytoskeleton. Tubulin is also a component of microtubules but was not selected in the provided answer.

Question 2:

Motor proteins use ATP for movement. They convert the chemical energy of ATP into mechanical work to move along cytoskeletal filaments. Passive diffusion is not how motor proteins move.

Answer:

Question 1:

B. actin, C. dynein

Question 2:

A. uses ATP to move
