Document Summary

Fermentation cont"d: muscle cells use fermentation during heavy workout and produce lactic acid (a 3 carbon sugar) (figure 9. 21a) Pyruvate accepts electron from nadh to make lactate. Allows the cell to keep making atp from glucose: yeast use fermentation and produce ethanol + co2 (figure 9. 21b) Allows the cell to keep making atp from glucose. Aerobic respiration using o2: 29 atps per glucose. Fermentation: anaerobic (occurs in absence of o2, yields only 2 atps per glucose. Metabolic pathways can be: catabolic pathways. The breakdown of sugars, fats, and proteins for producing atp: anabolic pathways. The synthesis of larger molecules from smaller components. Catabolic intermediates used in anabolic pathways: figure 9. 3. Photosynthesis: the process of converting the energy of sunlight into carbohydrates. Autotrophs: organisms that make all their own food from ions and simple molecules, example: photosynthetic organisms. Heterotrophs: organisms that derive their food from other organisms.
