Cell membrane parts and functions quizlet

Cells are limited in size because the outside (the cell membrane) must transport the food and oxygen to the parts inside. As a cell gets bigger, the outside is unable to keep up with the inside, because the inside grows a faster rate than the outside. The Golgi apparatus is an organelle present in most eukaryotic cells. It is made up of membrane-bound sacs, and is also called a Golgi body, Golgi complex, or dictyosome. The job of the Golgi apparatus is to process and bundle macromolecules like proteins and lipids as they are synthesized within the cell. Start studying Cell Functions.

The cell membrane functions as a barrier, keeping cell constituents in and unwanted For example, receptor-mediated endocytosis enables cells to ingest molecules such as proteins that are necessary for normal cell functioning.A membrane is held together primarily by hydrophobic interactions. The mosaic aspect of the fluid mosaic is a collage of different proteins, often clustered together in groups, embedded in the fluid matrix of the lipid bilayer. Phospholipids form the main fabric of the membrane, but proteins determine most of the membranes function. Cell Junctions. Junctions between cells most occur on or very near the cell's plasma membrane, but can also involve the tiny space between cells and sometimes the layer of cytoplasm that lies just below the plasma membrane. These junctions mostly fall into three categories which depend on the function they serve.
