  1. Have out: • Chemistry of Life notes (Pg. 3) • Compounds foldable (Pg. 9) Week #9 (9/14-9/18) Warm Up – Mon, 9/14: - Special Chemicals of Life video clip Biology Fun Fact: Today’s Learning Targets: - Describe the difference between an organic & inorganic compound. - Identify & explain the molecular structure of the 4 macromolecules necessary for life. Homework: 1. Study for the Biochemistry Unit Test – Wed, 9/16 & Thurs, 9/17 • Agenda: • Acids & Bases lecture • Inorganic & Organic Compounds needed for life Unit Learning Goal: I will understand the atomic & molecular structures that are required by all forms of life.

  2. Pg. 3 – Unit 2: Chemistry of Life note packet The pH of Nature video clip Acids & Bases • Solutions(solute + water) can be determined to be either an acid or a base. Here how it works… • A few (1 in 550 million) water molecules spontaneously split into ions. • Pure water has equal amounts of H+ & OH- ions. This is considered neutral. • Acidshave higher amounts of H+ ions. (#26) • Bases have higher amounts of OH- ions. (#27) • pH measures the concentration of hydrogen (H) ions in a solution. • Lower pH means a higher concentration of H+ ions (#28)

  3. Pg. 3 – Unit 2: Chemistry of Life note packet What is pH? • The pH scale is used to measure the relative acidity or alkalinity of solutions. (#28) • 7 (middle of the scale) is considered neutral. • Anything approaching zero (0-6.9) is more acidic. • Anything approaching 14 (7.1-14)is more basic or alkaline. (#29)

  4. Pg. 3 – Unit 2: Chemistry of Life note packet What is pH? • “pH” stands for the potential/power of Hydrogen. • pH is a logarithmic scale, meaning that an change of 1 pH is actually a tenfoldincrease or decrease in the H+ concentration of the solution. (#30) • Beer is 10 times (101) more acidic than tomatoes. • Stomach acid is 1000 (103) more acidic than tomatoes.

  5. Pg. 3 – Unit 2: Chemistry of Life note packet pH & Homeostasis • Blood requires a pH of 7.35-7.45. • Acidic, basic or neutral? • Sweat has a pH between 4.0-6.8. • Acidic, basic or neutral? • Saliva pH is normally around 6.0. • Acidic, basic or neutral? • Blood & other body fluids contain buffers, which can “absorb” increases on H+ (acid) or OH- (base) ions. • This keeps blood pH within a narrow range, no matter how acidic or alkaline your diet is.

  6. Levels of Organization of Life Organism (You & me) What are VERY LARGE molecules called? Organ System (Circulatory System) Organ (Heart) Tissue (Muscle) Cell (Nerve Cell) Organelle (Nucleus) Macromolecule (DNA) Molecule & Compounds (Amino Acid) Atom (Oxygen)

  9. Organic compounds– compounds with a Carbon-based core that are produced by living organisms(plants or animals) Usually contain hydrogen (H), carbon (C), oxygen (O) & nitrogen(N) together in large molecules called macromolecules Cells(life) are made of these compounds Carbon atoms enable these compounds to bond over & over in long durable chains Examples: carbohydrates, lipids, proteins, nucleic acids Organic vs. Inorganic COMPOUNDS Pg. 9 – Compounds Foldable On the BACK Per.4
