Discriptive investigation never include a hypothesis.
Transport proteins (carrier proteins and channel proteins) allow substances into and out of the cell that cannot pass through the phospholipid bilayer (as they’re either to large, charged or not lipid soluble) by facilitated diffusion.
Specifically channel proteins allow ions into and out of the cell by creating a pore in the membrane in which they can move through with their concentration gradient
The answer for this would just be your opinion.
how confident are you in answering the question, if you are not confident than say you aren’t and try to explain it to the best of your ability.
