Chapter 2 What is a buffer? Why are buffers important to living organisms? How do buffers work? Chapter 3 Why is the charge of an AA due to its side chain? How can the same amino acid have SLIGHTLY different pKa values when in different parts of the same protein? Why do pKa values experimentally deviate from published values? Under physiological conditions an amino acid like glycine – has a net charge of what Uncharged, why? Each amino acid has at least two pKa’s, explain? Histidine has three pKa’s, why? What does it mean if the pKa of an amino acid R group is 7? Chapter 4 When is cis/trans decided? What is the average number of residues per turn Where do you think amphipathic helices are located? What amino acid is frequent found in turns ? Chapter 5 Proteolytic enzymes: What do they hydrolyze? Table 5.3: Are these reactions always spontaneous? An enzyme speeds a reaction by lowering the activation energy.

Unformatted text preview: How would one depict this? In order for an enzyme to catalyze a reaction what must happen first? Chapter 6 What about arrows? Enzymes catalyze both the forward and reverse rates. Figure 6.1 What was the constant here? What was the variable? Extra Describe why buffering is such an important part of living organisms, include a molecular example. How does the primary structure of a protein (e.g. collagen, myoglobin) relate to its overall folding and/or function? How do conformational changes occur? How do conformational changes contribute to the function of proteins? Explain the advantage for cells to maintain intracellular substrate concentrations within the range of 0.1 Km to Km. Regulatory enzymes in metabolic pathways are often found at the first step that is unique to that pathway. How does regulation at this point improve metabolic efficiency?...
