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
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
Chapter 4 Notes
Protein Structure and Function
We concentrate on proteins in this book because they execute nearly all cell functions.
Proteins are found:
o embedded in cell membrane
o carriers of messages from one cell to another
o serving as tiny
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.
Chapter 1 Notes
Introduction to Cells
Cells are the simplest forms of life - the fundamental units of life -> cell biology studies these cells to
find out what life is and how it works.
UNITY AND DIVERSITY OF CELLS
We assume that cell of different
