Document Summary
Metabolism 8. 1-8. 4,9. 1: metabolism, sum of all chemical reactions and energy transformations in an organism, regulated to maintain homeostasis. Temp, ph, solute concentration, etc: an emergent property of living things. C. 2. due to orderly interactions between molecules seen at higher level of organization. C. 2. a) can"t be simply predicted: metabolic pathways. Begins with a specific molecule, ends with a product. Each step catalyzed/sped up by a specific enzyme. 2 types of metabolic pathways: anabolic and catabolic. Anabolic synthetic/building simple molecules complex (d. 3. a. 1) (d. 3. a. 2) (d. 3. a. 3) requires e (d. 3. a. 4) example: synthesis of protein from amino (d. 3. a. 5) think: anabolic anorexia simple eating habits. Catabolic pathways (d. 3. b. 1) break down (d. 3. b. 2) complex molecules simple molecules (d. 3. b. 3) releases energy (d. 3. b. 4) ex: (d. 3. b. 4. a) cellular respiration (d. 3. b. 4. a. i) break down glucose. Energy (e) (d. 3. b. 5) think: catabolic cats people think they"re these complex animals but they"re just simple balls of fur : the capacity to do work (or supply heat, 2 forms of energy.
