1. YOUR BIO-MOLECULES EXAM IS ON FRIDAY.
I AM ALSO TAKING UP YOUR COMPOSITION BOOKS FOR A GRADE ON FRIDAY.
Make sure your TOC is caught up.
All 9 items are present.
Make sure your Objectives are marked (what we did for a bellringer yesterday)
Intro, Protein, Carbs/Lipids, and Nucleic Acid notes have an essential question, 2 side questions, and an answer to the essential question at the bottom.
Bellringer goal from yesterday is completed.
Pizza Mush Lab is Completed
ALL SHEETS MUST BE GLUED OR TAPED.

2. Brainstorm with your group…
There are four Bio-Molecules
There are six cards that go with each Bio-Molecule Subunit/Monomer A picture In your body Out of your body Fact one Fact two
See how well you can match the cards with the correct Bio-Molecule.
Call me over when you are finished.

3. FACT 1 IN YOUR BODY FACT 2 OUTSIDE YOUR BODY
They are made of a 1:2:1 ratio of Carbon: Hydrogen: Oxygen.
This is where this biomolecule get it’s name.
• Is stored as glycogen (in muscles and liver) for energy
• Broken down in the cells to make ATP
Monosaccharide
-made ONLY of Carbon, Oxygen, and Hydrogen
FACT 2
OUTSIDE YOUR BODY
• In the cell walls of bacteria, plants, and fungus.
• Is stored as starch (in plants) for energy
This biomolecule is the #1 source of energy.

4. • Everywhere: skin, hair, muscles, bones
FACT 1
IN YOUR BODY
• Everywhere: skin, hair, muscles, bones
Includes enzymes, which help break other molecules apart AND put them together.
• In the plasma membranes of all your cells to help transport molecules in and out of the cell.
Amino Acid
CONTAINS NITROGEN
Each Amino Acid has a ‘R group’ that varies with each amino acid molecule
FACT 2
OUTSIDE YOUR BODY
They are also called ‘poly-peptides’ because the bonds in between it’s building blocks are called ‘peptide bonds’.
• All meats
• Nuts and beans

5. FACT 1 IN YOUR BODY FACT 2 OUTSIDE YOUR BODY
• Hormones: steroids, such as estrogen and testosterone
Insoluble in water (cannot dissolve)
• Most of your plasma membrane is made of this type of biomolecule
Fatty Acid Tails
Long chains of Carbon and Hydrogen
FACT 2
OUTSIDE YOUR BODY
Long time energy storage.
• Oils
• Waxes

6. FACT 1 IN YOUR BODY FACT 2 OUTSIDE YOUR BODY
• DNA which makes up your chromosomes.
Information storage in the form of a code
• RNA, used in protein synthesis: mRNA the messenger, rRNA the ribosome, tRNA the amino acid supplier.
Nucleic Acid
Contains a sugar, phosphate group, and nitrogenous base (ATCG)
FACT 2
OUTSIDE YOUR BODY
The closer the sequence to another organism, the closer you are related.
• Found in all living things in different amounts.
• Also found in small amounts in viruses.
