About You On a sheet of paper:
Legal Name Nickname you’d prefer Grade (please use your professional address) Favorite Academic Subject (PE and Lunch don’t count) Favorite Book(s) Favorite Movie(s) / TV Show(s) Random Fact About You Introduce yourself by saying your name, nickname, grade, and a “fave”
8
Nutrition Work with your partner.
Write down everything you ate yesterday and today. Put these food items into any categories that you believe make sense. You must have 3 or more categories. You must have a rational explanation for each category. Write down your explanation in complete sentences and with academic language.

The Chemistry of Biology
Chemistry Basics Matter: Everything w/ space & matter. All life, too! Atoms: Building blocks of matter; can’t see them. Hydrogen Atom (H) Particles in Atoms Electron (e-): negatively charged Proton (p+): positively charged Neutron (n0): no charge Outside (1e-) - + Atom H overall charge = 1e- + 1p+ + 0n0 = 1(-1) + 1(1) + 0(0) = = 0 Nucleus (1p+, 0n0) “center”

The Chemistry of Biology
Boron Atom (B) Outside (5e-) B overall charge = 5e- + 5p+ + 6n0 = 5(-1) + 5(1) + 6(0) = = 0 Nucleus (5p+, 6n0) Image Source:

The Chemistry of Biology
Elements: Pure substance; one type of atom. SPONCH: Elements of life; 99.8% of all living things. S: sulfur % P: phosphorus % O: oxygen % N: nitrogen % C: carbon % H: hydrogen % % of Human Body
16
The Chemistry of Biology
Molecule: Group of atoms bonded together. Molecular Oxygen (Gas) O2 Carbon Dioxide (Gas) CO2 Glucose Sugar (Solid) C6H12O6 Water (Liquid) H2O Image Source: homebrewsake.com

The Chemistry of Biology
Macromolecules: Big biological molecules; polymers. Levels of Organization “Large” “Life” “Many” Protons Electrons Neutrons Atoms Molecules Monomers Macromolecules/ Polymers Cells Organisms Chemistry Biology
19
Polymer/Macromolecule
Macromolecules Monomers: Molecules that link to make macromolecules/polymers. 4 Main Macromolecules “one” “many” monomer – monomer – monomer polymer/macromolecule Class Polymer/Macromolecule Monomer Carbohydrates Carbohydrate / Polysaccharide Monosaccharide Lipids Lipid Glycerol Molecule + Fatty Acid Tails Proteins Protein / Polypeptide Amino Acids Nucleic Acids Nucleic Acid Nucleotides
20
Carbohydrate / Polysaccharide
Macromolecules Carbohydrate / Polysaccharide (Macromolecule) Monosaccharide (Monomer) Function: Store short term energy Food Sources: Grains (carbohydrate), Candy (Monosaccharide) Connections: “Carb-Loading” before a race. Monosaccharide (“Simple Carbs”) Glucose Molecule “Sugar” Carbohydrate / Polysaccharide (“Complex Carbs”)
21
Macromolecules Lipid (Macromolecule) *technically not a polymer*
Glycerol Molecule + Fatty Acid Tails (Building Blocks) *technically not monomers* Function: Store long term energy, cushioning Food Sources: Oils, Fats, Waxes Connections: Fat cells synthesize & breakdown lipids Zoom-In Glycerol Molecule Polar / Hydrophilic (Loves Water) Fatty Acid Tails (Any #) Nonpolar / Hydrophobic (Hates Water) Lipid
22
Side chain changes for each of the 20 amino acids.
Macromolecules Protein / Polypeptide (Macromolecule) Amino Acids (Monomer) Function: Enzymes, Hormones, Structural Support, Cell Communication Food Sources: Meat, Eggs, Beans, Soy, Milk Connections: Protein powder to “build muscle”. Zoom-In H2N C COOH H R Leu Phe Ser Cys Protein Side chain changes for each of the 20 amino acids.
23
Macromolecules Nucleic Acid (Macromolecule) Nucleotides (Monomer)
Zoom-In P Nucleotide Nucleic Acid P = Phosphate Group = Sugar (“-ose” = Nitrogenous Base Key Image Source:
24
Macromolecules Nucleic Acid (Macromolecule) Nucleotides (Monomer)
Function: Store and transmit genetic information; “blueprints” Examples: DNA (deoxyribonucleic acid) RNA (ribonucleic acid) ATP (adenosine triphosphate) P ATP Break this bond for ENERGY! Nucleic Acids deoxyribose sugar ribose sugar Nucleotide

Reading / Work Time Read Chapter 5 Ch5: The Molecules of Life
Take Cornell notes on each section. After you are done reading, answer CONCEPT CHECKS at bottom of Sections 5.1, 5.2, 5.3, 5.4, and 5.5. Do the Chapter 5 Review Questions 1-20 Come show me reading notes when you are finished. Ch5: The Molecules of Life Organic Molecule Monomer Polymer Carbon-based molecules used in living organisms. Small molecular units that build a larger molecule Long chains of monomers linked together in a long chain. Examples are carbohydrates, lipids, proteins, and nucleic acids. Etc…. Summary: Macromolecules are the building blocks of living organisms. They are made up of smaller units called monomers. There are four types: carbohydrates which provide fuel, lipids which provide insulation, proteins which are responsible for day-to-day functioning of organisms, and nucleic acids which are the genetic material of an organism. The monomers they are made up of… etc…
