1. Macromolecules:
Essential Question: What are the four macromolecules and what are their roles in the body?

2. The 4 Macromolecules
Proteins
Lipids
Nucleic Acid
Carbohydrates

3. Carbohydrates Sugars & Starches
Main source of energy for living things
Generally end in “-ose”
We have talked about carbs before! When?
Photosynthesis-makes glucose
Cellular Respiration-Break down glucose to make ATP

4. Lipids Found in fats and oils
Make up the cell membrane (phospholipid bilayer)

5. Nucleic Acid Stores and transmits genetic information
Made of nucleotides
DNA (Deoxyribonucleic Acid)
Double stranded
Adenine pairs with Thymine (A-T)
Guanine pairs with Cytosine (C-G)
RNA (Ribonucleic Acid)
Single Stranded
Adenine pairs with Uracil (A-U)

6. Proteins Proteins are composed of amino acids
They have a variety of uses in the cell
Control the rate of reactions
Regulate cell processes
Form important cellular structures
Transport substances in and out of cells
Help fight disease
