Document Summary

Life: the science of biology, by sadava et al, 10th edition, volume 1. Complex chemical transformation occurs in a series of separate reactions that form a metabolic pathway. Each reaction is catalyzed by a specific enzyme. Many metabolic pathways are similar in all organism, from bacteria to humans. In eukaryotes, many metabolism pathways are compartmentalized, which reactions occurring inside specific organelles. Can be inhibited or activated to alter the rate of the pathway. Extract energy stored in the covalent bonds of glucose and stores it instead in atp. Glycolysis- begin glucose metabolism, anaerobic (no air o2) process because it does not require o2. Cellular respiration- uses o2 from environment, aerobic (with air o2) Fermentation- anaerobic, convert pyruvate into lactic acid or ethyl alcohol (rice wine) Reduction- gain of one or more electrons by an atom. Reducing agent a is oxidized losing electrons (losing electron because it is e-) e- subtract.
