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

The 4 Macromolecules Proteins Lipids Nucleic Acid Carbohydrates

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

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

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)

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

Protein Mini-Project You will be given a card that has the name of a protein. Research the following information for your advertisement/flyer. Do not write anything you do not understand. Use multiple sources.
