Bio 3: Homework #3 1. An electron carrier catches excited electrons and moves them to some other location to do work. They are involved in both aerobic respiration and photosynthesis. An electron transport system is similar in shape to a staircase, and works the same way as a hydroelectric dam. Excited electrons fall down the staircase and ATP is released. They are found in the cristae in the mitochondria. 2. The three phases of aerobic respiration: a. Glycolysis- In cytosol (The solution in the cytoplasm). Glucose is consumed, and 2 pyruvates, 2 (net) ATP and 2 NADH are produced. b. Krebs cycle- In the matrix of the mitochondria. 2 pyruvates are consumed. 6CO (as waste), 2 ATP, 8 NADH and 2 FADH are produced. c. Electron Transport Chain- The crisate in the mitochondria. 2 NADH from glycolsis, 8 NADH from the Krebs cycle, 2 FADH and 6O are consumed. 32 ATP are produced and 6 H O are released as waste. 3.
