Row 1, Col 1 Cytoplasm of cell; 2 pyruvates, 2 ATP, 2 NADH Where does glycolysis occur? List 3 important products of Glycolysis.

1,2 Matrix of mitochondria Where does the Krebs cycle take Place – be specific.

1,3 Inner membrane of the mitochondria Where, specifically, is the ETC Located in the cell?

1,4 An extra step (redox reaction) that regenerates the NAD+ since there’s either no O2 to accept the e-, or there’s no mitochondria in the cell (bacteria) Fermentation is basically Glycolysis plus …

2,1 No O2 is needed, all orgs do it, occurs in cytoplasm which all organisms have Why do scientists think glycolysis is one of the first energy Transforming reactions to evolve?

2,2 NADH & FADH2 What high energy molecules are Produced during the Krebs cycle And then transfer their energy To the ETC?

2,3 O2; from the atmosphere (humans breath it in, it diffuses into the blood vessels of fish gills, other , smaller creatures obtain it by direct diffusion with the environment.) What is the final electron In cellular respiration and where Does that molecule come from?

2,4 Cell respiration – it completely oxidizes glucose (food) where as the other two only split the glucose in half – partially oxidizing it. Which is most effective at Harvesting energy? Glycolysis, fermentation, cell Respiration and why?

3,1 Glucose, pyruvate, CO2 List the following molecules in order of most reduced to least reduced. Pyruvate, Glucose, CO2

3,2 Released as CO2 & H2O from cell respiration as the fat molecules are used for cellular respiration If your butt gets Smaller due to decreased Caloric intake and increased Burning of calories, where does It go? Literally?

3,3 Oxygen (which forms two covalent bonds with hydrogen after accepting the low energy electrons – forming water) What is the final electron acceptor In oxidative phosphorylation?

3,4 NAD+, lactic acid (lactate), ATP What final products are produced During lactic acid fermentation?

4,1 ATP & citrate Phosphofructokinase is inhibited By which two molecules?

4,2 With out it present to accept e- from the ETC, NAD+ and FAD+ wouldn’t be regenerated. Why is oxygen needed in The mitochondria for the Krebs cycle to occur, even though It’s not directly used in the cycle?

4,3 1) Cristae- folds allow for greater surface area for more copies of the ETC resulting in more ATP. 2) Inner mem allows for the creation of a concentration gradient. 3) proteins in ETC are sequenced such that each one is more electronegative than the previous – allows for e- to move “down” toward O2 Explain how the structure of the Mitochondria enables it’s Function. (be able to explain At least 2 structural characteristics)

4,4 Ethanol, NAD+, ATP, CO2 What final products are produced During alcoholic fermentation?

5,1 Action spectrum What shows the rate of Photosynthesis at various Wavelengths?

5,2 Acetyl Co-A, NAD+, FAD+, ADP Which of the following molecules Enter the Krebs cycle? Pyruvate, NADH, NAD+, CO2, ATP, ADP, glucose, FAD+, FADH2, O2, acetyl Co-A

5,3 The H+ gradient across the inner mitochondrial membrane (they diffuse through ATP synthase due to this) What is the most direct energy Source that powers the formation Of ATP during oxidative phosphorylation?

5,4 Not much O2 can diffuse through the dough to get to all the yeast cells so the yeast must produce ATP via alcoholic fermentation which produced CO2 gas as a waste product. This gas causes the dough to rise as it gets “stuck” in the dough. Bread is the product of baking a mixture of flour, water, salt, yeast and other ingredients. During it’s Baking, a beer-like odor is often detected. Explain how yeast makes bread Rise.
