How do small molecules move between the cytoplasm and nucleus?
A. Osmosis
B. Transport Proteins
C. Diffusion
D. Pores
Select all that apply
Homework Answers
Both Option C and D are correct.
Small molecules can freely pass through nuclear pore complex.
Answer:
The correct options are:
B. Transport Proteins
D. Pores
Explanation :
B. Transport Proteins: Small molecules often require transport proteins (like importins/exportins) to actively move through the nuclear pore complex (NPC).
D. Pores: Small molecules can passively diffuse through the nuclear pore complex (NPC) if they are within the size limit (~40-60 kDa).
Why Not the Others?
A. Osmosis: This refers to water movement across semipermeable membranes, not molecule transport between cytoplasm and nucleus.
C. Diffusion: While very small molecules (e.g., water, ions) can diffuse through NPCs, larger ones require transport proteins. Since the question specifies "small molecules," this could technically apply, but D. Pores is the more precise answer for nuclear transport.
