Extra Credit:
Students eligible for extra credit have all their assigned work for this chapter
turned in on time. Extra credit is
to be passed in before the test is taken (maximum
3 pts on test)
Build a
three-dimensional model of DNA and/or RNA that can be hung in the classroom.
Model should be neat, colorful and have a key to explain the parts of the
molecule.
Biochemistry
Links
ATP
Information and chemical structure of ATP
BioChem
links
List
of links that connect you to tons of biochem sites. Includes links to
general Biology and general chemistry topics.

After
you wade through the info on water (no pun intended) this site has lots of
links, pictures and info on the other biologically important molecules.
ATP
and Biological Energy
Way
more info than you could ever use as a high school bio student.
Reactions
and Enzymes
A
little technical but nice diagrams about how enzymes work in cells.
Photosynthesis
Information on the reaction that is vital to life on earth. Pictures too.
DNA
and molecular genetics
Page
geared more toward genetics but has some good info on DNA and some links to
pictures.
