Big Idea 2: Biological systems utilize free energy and molecular building blocks to grow, to reproduce, and to maintain dynamic homeostasis
P.S. In Biology we talk mainly about Organic Chemistry: The chemistry of molecules containing Carbon.
Susan was in chemistry.
Susan is no more,
for what she thought was H2O
was really H2SO4.
a. Molecules and atoms from the environment are necessary to build new molecules
Nitrogen moves from the environment to organisms where it is used in building proteins and nucleic acids. Phosphorus moves from the environment to organisms where it is used in nucleic acids and certain lipids.
Review of Chem
a. Structure and function of polymers are derived from the way their monomers are assembled.
Carbohydrates are composed of sugar monomers whose structures and bonding with each other by dehydration synthesis determine the properties and functions of the molecules. Cellulose vs. Starch. Why does one dissolve?
What doesbranching do?
Let’s go to the videotape!
can digest cellulose well; no need to eat other sugars
can’t digest cellulose well; must add another sugar source, like fruit to diet
Tell me aboutthe rabbits,again, George!
Nitrogen baseI’m the A,T,C,G or Upart!
Are nucleic acidscharged molecules?
H way their monomers are assembled.2O
Because everybody needs a Chaperonin!How are Proteins structured?
Just 1out of 146amino acids!
The nature of the bonding between carbohydrate subunits determines their relative orientation in the carbohydrate, which then determines the secondary structure of the carbohydrate.

HHow to build a polymer
You gotta be open to“bonding!
HOHow to break down a polymer
Breaking upis hard to do!
Any Questions?? polymer.
