Document Summary
(b) explain the effects of ph on enzyme catalyzed reactions. Acidic or basic solutions can alter charges by causing h+ or oh- to bind. Enzyme are affected by ph and temperature. For most enzymes, the effective ph range is 4-9. Active site works best at this ph. Activity decreases above and below the optimum. By interfering with h-bonding/active site structure (c) distinguish between the process of anaerobic respiration in yeast and humans. Glucose ---> pyruvate ---> ethanol & co2. Yeast: pyruvate to ethanol and carbon dioxide humans: pyruvate to lactic acid: (a) define metabolism. All of the enzyme-catalyzed reactions in a cell for organism. The reactions involve both the breaking down and building molecules. Glycolysis (c) describe cell respiration in terms of metabolism. Cell respiration reactions involve both breaking down and building up molecules. Cell respiration is metabolism because enzymes control the reactions. Energy is released from complex molecules to make atp.
