maintain (balance) or (equal state). Composition of the Cell Membrane & Functions: The cell membrane is also called the membrane and is made of a phospholipid The phospholipids have a (water attracting or polar) head and two (water repelling or non-polar) The head of a phospholipid is made of an alcohol and phosphate group, while the tails are 2 chains of fatty acids. Phospholipids can move apart and allow water and other molecules to pass through into or out of the cell. This is known as simple because it does not require and the molecules are moving from areas of concentration to an area of concentration. 1. LABEL a phospholipid bilayer coloring the heads red and the tails blue. 2. LABEL the structure that is hydrop and hydrophilic. PHOSPHOLIPID molecule membrane Another type of lipid in the cell membrane is that makes the membrane more stable. Embedded in the phospholipid bilayer are that also aid in diffusion and in cell transport. Proteins called proteins go all the way through the bilayer. They allow large molecules like and move across cell membranes. Some of the membrane proteins have carbohydrate receptors (look like chains) attached on the surface that are involved in cell recognition and ABO antigens on blood cells (blood type).

A group of BS Biology students were tasked to design and fabricate different synthetic cell membranes that could be used to simulate cellular activities of certain organisms. Below are the chemical structures of the compounds that are available to them: H2C-OH НС — ОН Но H2C-OH myristic acid glycerol HO alpha-linolenic acid Но—Р—о OH orthophosphate HO NH2 sphingosine OH CH2OH NH3 CH2OH Но ethanolamine Но. OH Но OH lactose HO (*point of attachment) Given these compounds, help the students assemble the structure of the lipid constituent for the cell membrane appropriate to study the following. Briefly explain your answer. а. a thermophilic bacteria thriving in a hot spring b. a hepatocyte of a sea lion in the Arctic Ocean С. a frog neurocyte
