Jan 07, 2021 · Membrane Structure and Function. Lecture Outline. Overview. The plasma membrane separates the living cell from its nonliving surroundings. This thin barrier, 8 nm thick, controls traffic into and out of the cell. Like all biological membranes, the plasma membrane is . selectively permeable, allowing some substances to cross more easily than others.

Membranes are mosaics of structure and function. A membrane is a collage of different proteins embedded in the fluid matrix of the lipid bilayer. For example, more than 50 kinds of proteins have been found in the plasma membranes of red blood cells. Proteins determine most of the membrane’s specific functions.
Chapter #7 – Membrane Structure And Function
Explain the function of the plasma membrane. Give the 3 functions of internal membranes in a cell. Give the general structure of a biological membrane. Make sure you can differentiate between a plant and an animal cell diagram and locate each of the organelles within each cell. Part C. Is the nucleus the only place where genes are located? Explain

The cell membrane, also called the plasma membrane,is made mostly of lipids. The lipids found in cell membranes are specifically called phospholipids. These lipids are arranged in a double lipid layer known as the phospholipid bilayer. Each phospholipid has a hydrophilic(water-attracting) head and two hydrophobic(water-repelling) tails.
