The short video segment below (3:36) is from Discovery Channel. It's a very basic introduction to cells, but may be of interest to students with little background in the sciences.
After successfully completing this section, the student will be able to:
- List and distinguish the major organic molecules (sugars and starches; amino acids and proteins, nucleotides and nucleic acids; fatty acids, phospholipids, trigylcerides, and cholesterol) and explain how polymers provide for increasingly complex molecules.
- Distinguish between covalent and ionic chemical bonds.
- Explain what is meant by a "polar" compound.
- Explain how the amphipathic nature of molecules enables the self-assembly of macromolecular structures such as the cell membrane.
- Describe the composition of the cell membrane.
- List the functions of protein molecules in cells. Define what is meant by "protein binding sites".
- Describe the three mechanisms by which proteins enable transport of substances across cell membranes.
- List and distinguish the hierarchy of organization within organisms (atoms -> molecules -> organelles -> cells -> tissues -> organs -> organ systems)
