Proteins in the cell membrane have many functions. Which type of protein would be used primarily to transport materials in or ou
S_A_V [24]

So we know that to transport materials in or out of the cell, we need to have access to both the inside and outside of the cell. This would require that the protein be a transmembrane protein that reaches both the inside and the outside of the cell.

So in this case, let's look at pore proteins. These are proteins that cross a membrane and act as a pore for the materials that need to cross the membrane.

One example of a pore protein is an aquaporin. These proteins aid in the transport of water into or out of a cell.

Therefore, the answer to your question is: A) Pore proteins.
