Structure of the atom
Given information from the Periodic table, you should be able to figure out the
number of protons, neutrons, electrons, atomic mass, or atomic number for any
element,
You should understand the structure and properties of the water molecule
Define the four categories of biological molecules. Know the monomer, dimer
and polymer for each category with examples. Know general functions of
examples in each category.
What are the four levels of organization of a protein?
What are the three parts of an amino acid or nucleic acid?
Definition only for Dehydration synthesis and Hydrolysis
Read molecular formulas with coefficients and subscripts
Compare endothermic vs. exothermic reactions
Compare the two theories of enzyme function: “Lock and key” and “Induced fit”
