There may be MORE THAN one correct answer. 1. is the first step in cellular respiration that begins releasing energy stored in glucose. A. Alcoholic fermentation B. Lactic acid fermentation C. Glycolysis D. Electron transport chain 2. The carriers for energy and high energy electrons resulting from glycolysis and the krebs cycle are A. ATP B. NADH CFADH2 D. NADPH 3. If oxygen is NOT present, glucose is broken down by A. Krebs cycle B. electron transport chain C. fermentation (anaerobic respiration) 4. Name the 3 carbon molecule produced when glucose is broken in half during glycolysis. A pyruvic acid B. lactic acid C. Acetyl-CoA D. citric acid 5. Since fermentation does not require oxygen it is said to be A. aerobic B. anaerobic 6. Write the complete overall chemical equation for cellular respiration using words: Sugar. Okygen ATP Carbon • dioxide. Water 7. Compare this reaction to PHOTOSYNTHSIS (6 H₂O 6 CO₂ light energy CH2O 602) How are these equations related? Opposites & dependent on each other 8.

Where do the carbon atoms in pyruvic acid end up following the Krebs cycle? A. They enter the electron transport chain and make ATP B. They become part of a carbon dioxide molecule and end up in the atmosphere C. They join with citric acid to make Acetyl-CoA D. They build up in the intermembrane space 14. When cellular respiration requires oxygen it is said to be A aerobic B. anaerobic 15.
