What are the properties that make water important to biological systems?
What are the differences between the three different types of bonds that make up biological molecules?
What is the difference between a structural formula and a molecular formula?
What does the pH scale tell you and how is it important to biological systems?
What are the characteristics of all living organisms?
How are buffers important to biological systems?
How do the four different structures of proteins differ from each other?
How does an enzyme increase the rate of chemical reactions?
What interactions can occur with the enzyme and another molecule to impact the ability of the enzyme to perform its functions?
What are the modes of facilitated transport and active transport and how are they different from each other?
What are the detailed processes of exocytosis and endocytosis and how do they work?
