Answer to relevant QuestionsUsing information from Table 15.1, calculate the value of DG°' for the following reaction. Glucose- + -phosphate → Glucose-6-phosphate Which of the following statements is (are) true about the modified standard state for biochemistry? For each, explain why or why not. (a) [H+] 5 1 3 10–7 M, not 1 M. (b) The concentration of any solute is 1 × 10–7 M. Starting with the open-chain form of d-ribose, write equations for the cyclization reactions that form the pyranose and the furanose forms. Why is the polysaccharide chitin a suitable material for the exoskeleton of invertebrates such as lobsters? What other sort of material can play a similar role? The M and H subunits of lactate dehydrogenase have very similar sizes and shapes but differ in amino acid composition. If the only difference between the two were that the H subunit had a glutamic acid in a position where ...
