Hacker in her synthetic biology lab, where she wants to change the world! In this simulation, you will learn about the structure and function of the cell membrane, and discover why membrane transporters are vital for healthy cells and the function of organ systems. Membrane Proteins. The lipid bilayer forms the basis of the cell membrane, but it is peppered throughout with various proteins. Two different types of proteins that are commonly associated with the cell membrane are the integral proteins and peripheral protein ().As its name suggests, an integral protein is a protein that is embedded in the membrane. The plasma membrane’s ability to control the passage of molecules across it is called selective permeability. The movement of materials into and out of the cell occurs in a variety of ways that can be categorized into two basic processes, passive transport and active transport.

-Substances move across cell membrane on their own, no energy is used or required-Two types of Passive transport: Diffusion-Facilitated Diffusion and Osmosis; and Filtration The cell membrane has many proteins, as well as other lipids (such as cholesterol), that are associated with the phospholipid bilayer. An important feature of the membrane is that it remains fluid; the lipids and proteins in the cell membrane are not rigidly locked in place.

transport of large particles, marcomolecules, and fluids across membrane in membranous sacs called vesicles, requires cellular energy; type of active transport functions of vesicular transport exocytosis, endocytosis, transcytosis, and vesicular trafficking

The plasma membrane can only be selective if the cell is healthy and unharmed Carrier Proteins for Active Transport. An important membrane adaption for active transport is the presence of specific carrier proteins or pumps to facilitate movement. There are three types of these proteins or transporters: uniporters, symporters, and antiporters.

Plasma Membrane • Function – Separate cell from environment – Transport substances in and out of cell – Receive and respond to stimuli • Properties – Hydrophobic and hydrophilic – Selectively permeable • Structure – Fluid Mosaic Model – Lipid bi-layer – phospholipids (75%), cholesterol (20%

Transport across the Cell Membrane One of the great wonders of the cell membrane is its ability to regulate the concentration of substances inside the cell. These substances include ions such as Ca ++ , Na + , K + , and Cl – ; nutrients including sugars, fatty acids, and amino acids; and waste products, particularly carbon dioxide (CO 2 ), which must leave the cell.

13.1 Passive Diffusion. The simplest form of membrane transport, passive diffusion, refers to the diffusion of a species by A. Luini, in Encyclopedia of Cell Biology, Active transport and passive transport are discussed under solute transport.
