Recitation will be available soon : Lecture: 4-ch3 Amino acids image-74 (00-31-42) For Weak Acids Topic question 3-ch2 Dissociation of Weak electrolytes : acetic acid Water as a Reactant Water is often a product or reactant in biological system. Condensation reactions typically produce a water as a side product. Hydrolysis reactions will use a water molecule as a reactant. ATP ADP Topic Question) 3-ch2 Draw a titration curve for phosphoric acid. Indicate pKa values and buffering zones. Why is buffering necessary? Maintenance of intracellular PH is vital to all cells. Enzyme-catalyzed reactions have optimal PH. Solubility of polar molecules depends oh H-bond donors and acceptors Gas exchange: equilibrium between CO2 gas and dissolved HCO3- depends on PH At wrong PH, certain functional groups are no longer in the right ionization state to perform a role. : Enzyme catalysis, protein folding Many reactions will take place over a small pH range, but perform optimally at a set PH. Biological Buffer Systems Integrate knowledge with other discipline Metabolic Acidosis and Hypoventilation Integrate knowledge with other discipline Topic question 3-Ch2. Diabetes and blood ketones Explain how diabetes contribute to high blood ketone and what are the symptoms.
