Document Summary
The cell"s flexible outer surface regulated the flow of materials. All of the cellular contents between the plasma membrane and the nucleus. A large organelle with dna found inside it into and out of a cell; allows communication between cells and their external environment. Organelles-found in the cytosol and each have a different function. Chromosomes found within the nucleus contain genes that control cellular structure and function. Lipid bilayer the main structure of the plasma membrane: two back to back layers made up of 3 different types of lipid molecules: Two categories of proteins: ________________ proteins: extend into or through the lipid bilayer, what are transmembrane proteins, _________________ proteins: not as firmly embedded into the membrane and are attached to membrane lipids or integral proteins. Function of membrane proteins (put the words in the correct blanks) Endocytosis: what type of energy is used, receptor-mediated endocytosis- A network of protein filaments that extends throughout the cytosol.
