Proteins are scattered across the phospholipid bilayer that help assist the membrane's job of allowing only certain substances in and out of the cell. These proteins are known as membrane proteins. They are embedded within the phospholipid bilayer and play a crucial role in regulating the movement of substances across the cell membrane.

To understand how these proteins assist the membrane's job, you can employ two methods:

1. Research: You can explore books, scientific articles, or reputable online sources that provide detailed information about the structure and function of the phospholipid bilayer and membrane proteins. Scientific databases like PubMed or educational websites like Khan Academy can be excellent resources for gathering this information. By reading and understanding the concepts, you will gain valuable insights into the role of membrane proteins in controlling the selective permeability of the cell membrane.

2. Consult experts: Another way to learn about membrane proteins and their role in the cell membrane is by consulting experts in the field. You can reach out to biology professors, researchers, or professionals who specialize in cell biology, membrane biology, or biochemistry. They can explain the topic in detail, point you towards reliable resources, and answer any specific questions you may have.

By combining both research and expert advice, you can gain a comprehensive understanding of how membrane proteins assist the membrane in allowing only certain substances in and out of the cell.

Proteins are scattered across the phospholipid bilayer that help assist the membrane's job of allowing only certain substances in and out of the cell. There are two types of proteins that serve this purpose: integral proteins and peripheral proteins. Integral proteins are embedded within the phospholipid bilayer, while peripheral proteins are loosely attached to the surface of the membrane. Both types of proteins play critical roles in maintaining the selective permeability of the cell membrane and regulating the movement of substances across it.
