1. What one atom is the most important in allowing life on Earth? (lab) 6 Properties of Water

3. The study of all compounds containing carbon, oxygen, nitrogen, and hydrogen is called organic chemistry Carbon can bond to make long chains like no other atom can do.

4. “Giant Molecules”

5. 4 Classes of organic molecules 1.Carbohydrates (sugars and starches) 2.Proteins 3.Lipids (fats) 4.Nucleic Acids (genetic material) *each of these are made from smaller subunits LEGO ANALOGY

6. The main source of energy in living things! Carbohydrate is a fancy word for SUGAR (glucose). *Anything ending in -ose is a carb. Monosaccharide- a single sugar molecule. ex. Glucose (simple sugar) Polysaccharide- many sugars strung together. ex. Starch (complex carb)

7. Your body uses carbohydrates for immediate sources of energy (turns into ATP). This is why it is so important to keep blood sugar balanced. Think Diabetes.

8. Strings of amino acids combine to make proteins with very specific shapes and functions. Their shape is what gives them their job. Their shape is due to the sequence of amino acids that makes them up.

10. Highly Sensitive!!! If pH or temperature changes, shape will change and they will not be able to work properly.

11. Made mostly of carbon and hydrogen, lipids store energy A fancy word for FATS. Some can be used as a waterproof covering to surround cells.

12. Considered to be “hydrophobic” They DO NOT like to mix with water. Includes waxes, fats, etc.

13. NUCLEOTIDES combine to make nucleic acids. These are DNA The order of nucleotides in your DNA holds the code for all of your body’s proteins to be made.

14. Building Blocks!!! Carbs = sugars starches made of simple sugars Proteins made of amino acids (A.A.s) Nucleic Acids made of nucleotide bases

15. Which of the four groups of molecules is responsible for giving us our main source of energy? (lab) Properties of Water
