4 The Chemical Basis of Life
5 The Molecules of Life
6 A Tour of the Cell
Objectives
1. You should be familiar with the big bang theory of the origin of the universe
and how this theory is related to the origin of atoms.
2. You should understand the Doppler effect for light and sound and know how
this relates to the evidence suggesting the universal expansion.
3. You should understand the organization of the periodic table and be able to
use it as a reference to determine information about the elements in the first 3
rows.
4. You should understand why atoms form compounds and be familiar with the
two manners in which they do so.
5. You should be able to diagram and describe how given atoms form specific
ionic or covalent bonds.
6. You should be familiar with the stages through which Earth’s atmosphere has
evolved and understand how the atmosphere influence the development of
life and how life influenced the development of the atmosphere.
7. You should be familiar with the two major portions of a cell and know the
component molecules or structures that are found in each.
8. You should be familiar with the molecules that compose the cell membrane
and be able to diagrams and describe why the membrane form in the manner
that it does (with relation to water) as well as the functions of the various
components of the cell membrane.
9. You should be able to estimate the size of cells and know why cells are limited
in their size with reference to the relationship between surface area and
volume.
10. You should be able to compare and contrast the various categories of cells
that are found in living things (plants, animals, bacteria), and describe the
process and evidence for the endosymbiotic development of organelles.
10. You should be familiar with the manners by which substances move into
and/or out of a cell and understand the processes that influence these
movements.
11. You should know the various characteristics of enzymes.
12. You should know the function of the cell in general and be able to explain
how the components of the cell support this general function (water among
them).
