Capitol Report: Iranâs Global Threat. This week, I voted to stop the dangerous deal the Obama Administration negotiated to lift sanctions on Iran. I voted to protect Americans from the global threat posed by a nuclear Iran, because this is not a Republican issue or Democrat issue; this is an American security issue.
Cell Membrane Structure. The cell membrane is primarily composed of a mix of proteins and lipids. Depending on the membraneâs location and role in the body, lipids can make up anywhere from 20 to 80 percent of the membrane, with the remainder being proteins.
What makes up the cell membrane? How does it do its job so the cell can complete its own purpose within the body? The job of the cell membrane is to protect the cell from the environment outside and from other cells. The membrane also dictates what can come into the cell and what can leave. It is not rigid or solid like a wall, rather it is closer to the consistency of cooking oil, and yet it still manages to do its job within the cell.
