The cell membrane is made up of many different kinds of proteins. these proteins can be classified as either peripheral, transmembrane, or lipid-anchored proteins. regardless of their classification, these proteins all play an important role in the function and integrity of a cell. which of the following properly describes the function of membrane proteins? - to allow for cell-cell communication
- to serve as a channel for the transport of molecules between extracellular and intracellular fluid
- to provide structural stability for the cell
- to combine with a carbohydrate, providing an immune response and/or cell recognition

To serve as a channel for the transport of molecules between extracellular and intracellular fluid.

Explanation:

The composition of cell membrane shows that the cell membrane is composed of the lipids, cholesterol and the proteins in the cell membrane.  

These proteins could be embedded in the cell membrane layer called "integral membrane" or "membrane proteins" and attached to either the inner or outer layer of the cell membrane called "peripheral proteins".

The membrane proteins which are embedded in the membrane form channel proteins which allow the selective transport of the molecules, ions and other substances into and out of the cell.

Thus, the selected option is the correct answer.

she will be charged $6

step-by-step explanation:

48 dollars divided by 200 beads equals .24 dollars a bead

.24 multiplied by 25 more beads equals 6 dollars as the total cost
