This is my groups poster of a fluid mosaic membrane!!
This is a picture my group drew of a fluid mosaic membrane. It consists of phospholipids connecting together due to the fact that they are hydrophobic. They happen to form a well structured wall or barrier to coincide with the cell's protection. Many different proteins also make up the wall, these proteins vary in functions from helping the membrane move to storing nutrients it needs. Inparticularly the transport protein allows molecules through the wall that are needed to be retrieved by the cell. Receptor proteins also play a major roll inside the cell, such as the fact that they connect and communicate with other cells. The recognition proteins lets the other cells know what type of cell it is and what organism it may be from.

More About Membranes
Biological membranes tend to form as a type of collage of proteins that come together to coincide in the fluid matrix in the lipid bilayer. The lipid bilayer is the main fabric of almost any membrane, and within its structure a semi-permeable membrane is constructed. Proteins determine most of the membrane's specific functions. The plasma membrane and the membranes of the various organelles each have unique collections of proteins. For example, more than 50 kinds of proteins have been found in the plasma membrane of just one single red blood cell. In one tiny cell thats INCREDIBLE!!!
Extra Information!!!
Functions within the Cell
Cholesterol: Manages the fluidity of the membrane especially as the weather begins to change.
Transmembrane Protein: Transports items within the molecule
Channel Proteins: These are tubular, and allow passage of molecules through the membrane
Carrier Proteins: Combines with substances to be transported, and assists in the passage of molecules through the membrane
Cell recognition proteins: Provide unique chemical ID for cells, and helps the body recognize foreign substances
Receptor Proteins: They bind with messenger molecules, and cause the cell to respond to the message
Enzymatic Proteins: Carry out metabolic reactions directly
Plasma Membrane: is differentially (selectively) permeable, allows some material to pass, and inhibits passage of other materials
Passive transport: no ATP requirement-energy, molecules follow concentration gradient
Active transport: requires carrier protein, requires energy in form of ATP
-The red circles of this image are known as the "heads" or phosphates of a membrane structure. These "heads" are polar and hydrophilic.
-The blue squiggles are known as "tails" or fatty acids of a membrane structure. These "tails" are non-polar and are hydrophobic.
This poster was designed by Brainna, Ashley, Desiree, Vannessa and David. However it had a couple more parts to the fluid mosaic membrane structure that I thought would be important to add to my own poster and post. Such as the integral protein which
-This website was particularly helpful to my understanding of the mosaic membrane structure and some of the other corresponding components that it consists of, so I decided to share it with the rest of you bloggers!!!
