Chapter 4 Notes
Protein Structure and Function
We concentrate on proteins in this book because they execute nearly all cell functions.

Chapter 3 Notes
Energy, Catalysis, and Biosynthesis
Will discuss why cells require energy, how that energy is used -> enzymes and enzyme kinetics.
Enzymatic reactions are not isolated events, but usually connected together so that the product of th
Chapter 2 Notes
Chemical Components of Cells
Everything in biology obeys both chemical and physical laws.
All matter is made of combinations of elements - substances that cannot be broken down into other
substances by chemical means.
HOW PROTEINS ARE STUDIED
BREAKING CELLS AND TISSUES
First step is to disrupt tissues and cells by homogenization -> ruptures cell membrane and cell contents
There are 4 commonly used procedures:
1) sonication - u
