Homework Answers
a. carbohydrate chain-these are also called as glycolipids and glycoproteins give each cell a unique fingerprint,allowing cell to adhere to one another,to receive signals from various molecules and to recognize other cells.
b.cholesterol- makes phosopholipids pack more tightly and regulates fluidity and flexibility of the membrane.
c.proteins- it transports chemicals and information throughout the membrane.
d.phospholipid bilayer- it is a liquid membrane in which other molecules such as proteins are suspended.
e.filaments of cytoskeleton- it provides internal support for the cells

Lo 8: Properties of the Plasma Membrane 1) Draw the structure of a phospholipid and label the three parts: Glycerol backbone, fatty acid tails and phosphate head group. Label which regions are hydrophobic and which are hydrophilic. Be able to explain WHY they have the property they do (think of their chemical make up-look it up if you need a reminder). 2) Describe two properties that affect membrane fluidity? Draw a representation of how each property affects membrane fluidity. Explain...
