  1. Business • Starbucks Review – Sunday 1 pm (I-10 and Garth) • Test – Monday • “Lab” – Tuesday

  2. For the lab… • For your group’s results, write a statement about what your results would indicate, then DISCUSS (which means give several reasons and explanations why your results may have turned out that way and DISCUSS at least 3 improvements for the lab design • Results = statement • Explanation = discussion • Improvements = discussion

  3. Leave room for your discussion… • Write how the following SHOULD have affected the rate of photosynthesis: • Increased light intensity  • Red, yellow, green, blue, clear light  • Increased CO2 concentration  • Darker leaved plants (spinach vs. tree)  • Increased temperature 

  4. ATP, Enzymes, CR, and Photosynthesis Jeopardy ATP &Enzymes make the biosphere go ‘round Cellular Respiration – so you can live Dear plants, thanks for the O2 Pick-a-Process! Random Trivia 100 100 100 100 100 200 200 200 200 200 300 300 300 300 300 400 400 400 400 400 500 500 500 500 500

  5. Which of the following is the likely order that the biochemical processes evolved? • Oxidative phosphorylation, glycolysis, photosynthesis • Photosynthesis, glycolysis, oxidative phosphorylation • Glycolysis, oxidative phosphorylation, photosynthesis • Photosynthesis, oxidative phosphorylation, glycolysis • Glycolysis, photosynthesis, oxidative phosphorlyation 1,100

  6. Carbohydrate-synthesizing reactions of photosynthesis directly require (A) light (B) products of the light reactions (C) darkness (D) O2 and H2O (E) chlorophyll and CO2 1,200

  7. The carbon that makes up organic molecules in plants is derived DIRECTLY from (A) combustion of fuels(B) carbon (from CO2) fixed in photosynthesis(C) carbon dioxide produced in respiration(D) carbon in the lithosphere (E) coal mines 1,300

  8. All of the following would INCREASE the production of glucose in photosynthesis EXCEPT (A) Higher concentrations of carbon dioxide in the atmosphere (B) Reduced carbon dioxide concentrations in the air spaces of the leaf (C) Increased intensity of light (D) Increased frequency of stomatal openings (E) More Calvin cycle enzymes (like RuBisco) 1,400

  9. Dichlorophenolindophenol (DPIP) is a blue dye that is decolorized when it is reduced.After being mixed with DPIP, which of the following would show the greatest change in color? (A) Isolated chloroplasts in the light (B) Isolated chloroplasts in the dark (C) Chlorophyll extract in the dark (D) Boiled chloroplasts in the light (E) Boiled chloroplasts in the dark 1,500

  10. Which of the following directly produces the most ATP per mole of glucose during aerobic cellular respiration? (A) Glycolysis (B) Electron transport chain and chemiosmosis (C) Substrate-level phosphorylation (D) Kreb’s Cycle (E) Alcoholic fermentation 2,100

  18. ATP serves as a common energy source for organisms because (A) it is the smallest energy molecule (B) it stores the least energy of any energy source (C) its energy can be easily transferred to do cellular work (D) it is extremely stable and can be stored in the cell for long periods of time (E) traces of it have been found in fossils of ancient organisms dating back to the beginning of life on Earth 3,400

  19. Which of the following is INCORRECT about the diagram to the right? • The reaction is exergonic. • “D” represents the net energy change of the reaction. • “B” represents the activation energy for the enzyme-catalyzed reaction. • “E” represents the energy released as a result of the reaction. • All of the above are true. 3,500
