1. DID YOU KNOW?
Protein cannot be stored for later use, like fat or carbohydrates can, so the body needs daily replenishments.

2. OBJECTIVE
SWBAT LEARN ABOUT PROTEINS

3. WARM UP
A researcher is studying raccoons and skunks. She wants to find out how closely these two mammals are related. Which of these characteristics would be best for her to study?
sequences of DNA
reproductive habits
movement of RNA
physical appearance

4. MACROMOLECULE functions of proteins include
building and repairing of body tissues
regulation of body processes
formation of enzymes and hormones
Protein can come from diet; foods such as nuts, beans, and meats.

5. SUBUNIT OR BUILDING BLOCK
Proteins are made up of Amino Acids.
All amino acids end in “ine” (methionine, tyrosine, etc.)

6. ORGANELLE OR PART OF THE CELL
PROTEINS are made in the RIBOSOME from information on the RNA

7. PROCESS An example of PROTEIN is ENZYMES
ENZYMES end in “ase” (catalase, lactase)
ENZYMES ARE PROTEINS THAT SPEED UP REACTIONS
ENZYMES ARE AFFECTED BY 3 THINGS:
PH, TEMPERATURE, AND CONCENTRATION

8. CLOSURE
Which of these make up the primary link between a gene and the expression of a trait?
proteins
sugars
lipids
vitamins
