Only small molecules can diffuse through the nuclear pore complexes. A) True B) False
Understand the Problem
The question is asking whether only small molecules are able to diffuse through nuclear pore complexes, which are gateways in the nuclear envelope that permit exchange of substances between the nucleus and the cytoplasm.
Answer
False
False, because only small molecules can diffuse easily through the nuclear pore complexes, while larger molecules require active transport.
Answer for screen readers
False, because only small molecules can diffuse easily through the nuclear pore complexes, while larger molecules require active transport.
More Information
Small molecules can passively diffuse through nuclear pore complexes due to their size, whereas larger molecules like proteins and RNA require active transport mechanisms to cross.
Tips
A common mistake is misunderstanding that 'only' small molecules diffuse. Larger molecules can also pass but need active transport.
