& Concepts: The first two sections of this chapter
are largely review of last year's Physical Science
and you are expected to review this material on your own. See
your teacher for extra help if necessary. We expect you to be familiar
with the concepts of elements
Know the three subatomic
particles, their charges,
location in the atom, and relative masses. Be sure you
understand what an isotope
is; they are very important in biological research. Know the
differences between ionic
and covalent bonds and be able to write the molecular formulae of
ionic and covalent compounds. Appreciate that polar covalent and
Walls forces also play an important role in the behavior
of biological molecules such as proteins.
Appreciate that the
molecule plays an incredible important role in biology, in large part
due to its highly polar
structure. Understand why water is a polar molecule and be
able to discuss some of the properties that result. In particular,
understand that the polar nature of water has a profound effect on its boiling and freezing
temperatures, its cohesive
and adhesive properties, and its role as a solvent for a
great many substances. Also review your knowledge of solubility, pH, and acids and
bases. You are expected to be familiar with all of this
material from last year.

Concepts: Understand why atoms of the element Carbon are so
flexible and unique to the point where compounds containing carbon
atoms have the special classification as organic compounds.
Understand that these unique properties of carbon allow it to form very
Appreciate that these macromolecules are often constructed of smaller
subunits called monomers
linked together to form polymers.
Know the four major groups of macromolecules: the carbohydrates, lipids,
proteins, and nucleic acids. For each you should know
their basic structure,
how the monomers are linked,
in cells, and specific examples of each.
D. Read these
two articles from ScienceDaily
answer the following Questions. Due .

pages 57-58: 9-10, 22-25.
Concepts: Again, review your knowledge of chemical reactions
from Physical Science last year. Be sure you can "read" a chemical
equation, know if an equation is balanced, and be
able to classify chemical reactions as synthesis, decomposition,
single and double replacement. Know the difference between
an exothermic and
endothermic reaction and the role of energy in these
two types of reactions. Understand the significance of activation energy
in exothermic reactions. Be sure you appreciate the role of enzymes in the
reduction of activation energy and understand why this is particularly
important in cellular processes that depend on chemical reactions.
Understand how enzymes function by producing the enzyme-substrate complex and
the conditions such as temperature
that influence the activity of the enzyme.
