Make sure that you understand the concepts that we discussed.
Chapter 1:
What is a kingdom? What 6 kingdoms are recognized in Biology?

Anatomy & basic properties of an atom
Ions & Isotopes
C14 dating
Oxidation & reduction
Different types of bonds (ionic, covalent, hydrogen, peptide)
Important characteristics of water
pH scale & Buffers

Factors that affect enzyme function
How cells regulate Enzyme function
ATP structure & function
Chapter 6:
