To pass through the cell membrane, some molecules need to pass through a(n) _________ because they are too big to simply pass through the phospholipids.
Understand the Problem
The question is asking about the mechanism by which certain large molecules pass through the cell membrane. It requires identifying the correct type of channel that facilitates this process.
Answer
protein channel
The final answer is protein channel.
Answer for screen readers
The final answer is protein channel.
More Information
Molecules that are too large to pass through the phospholipids of the cell membrane use transport proteins, which function as channels or carriers.
Tips
A common mistake might be to think diffusion channels exist, but the term isn't typically used in biology.
