4 Set up your photosynthesis boards Walk around and look at all the boards for: -creative stationary pieces -creative moving pieces -overall display Rate your top 3

5 Cellular respiration C 6 H 12 0 6 + 6O 2  6CO 2 + 6H 2 0+ ATP

6 OIL RIG OIL=oxidation involves losing e- RIG=reduction involves gaining e-

7 NAD+ ---NADH NADH--electron holder. Can hold 2 e-. Electrons lose very little energy when they are transferred from glucose to NAD+

8 FAD—FADH2 FADH2 holds electrons FADH2 carries lower energy electrons than NAD+

9 ATP--ADP PHOSPHORYLATION... adding a phosphate to ADP ADP + P ------> ATP ATP holds more energy than ADP

10 Substrate level phosphorylation

11 ATP synthase

14 NO OXYGEN=Fermentation In fermentation to pyruvic acid molecules are turned into some “waste” product, and a little bit of energy (only two ATP molecules per molecule of glucose – actually four are produced in glycolysis, but two are used up) is produced. Out of many possible types of fermentation processes, two of the most common types are lactic acid fermentation and alcohol fermentation.
