A cell is making lots of a five carbon sugar that needs to be transported across the membrane into the blood to be taken way to other cells in the body. What would you expect to see in the membrane to facilitate transport?

There is a very well developed mechanism is transportation of the materials from the one part of the cell body to another as we can expect some of the proteins and lipids inside the membrane of the molecules.

There is a very well developed model for the transported of the molecules across the cell membrane in a proper way. As there are is two ways or nature of materials transportation inside the cell's membrane, and inside both the mechanisms the proteins are greatly involved in them, as the two mechanisms are:

Active transport of materials across the membrane,
Passive transport of the materials.

However, it is been confirmed after research that there is minimum amount of energy required to carry out the whole process of trans-portion of the materials and its only made possible through the protein channels inside the cell membrane's structure along with having the lipid bi-layer.
However, it is more obvious that these materials move across the cell membrane body due to the possible difference in there potential.

There are are also a number of molecules of the carbohydrates which make it possible for the whole process of material transportation across the membrane more easy.
