(a)

Summary Introduction

To determine and explain: The value of ΔG°' for steady-state concentration of 3-phosphoglycerate and 2-phosphoglycerate in human red blood cells as 61μMand4.3μM respectively. When given that K’eq for their inter-conversion reaction is 0.165 at 25oC and 7.0 pH value.

Introduction: Free energy of a system is that amount of energy that is used can be changed into work in a system provided that the temperature and pressure of the system remain the same. It is denoted by ΔG . Free energy is informative of the extent to which a reaction can proceed so that all the reactants and products can reach a concentration value of 1.0 M when the conditions are maintained the standard.

Please balance the reaction below. Considering the pe0 of Pb2+/Pb0 and O2/H2O are -2.13 and 14.5, respectively, will the oxidation of Pb0 by oxygen occur under conditions: pH 8, [Pb2+] = 5x10-8 M, [O2(aq)] = 2.5x10-4 M? Pb0 + O2 + H+ → Pb2+ + H2O
Chemical labeling of chymotrypsin by the compound tosylphenylalanine chloromethyl ketone (TPCK) modifies the His 57 in the enzyme's active site. The structure of this derivative is shown below. TPCK inactivates the enzyme because the bulky addition prevents it from cleaving nearby covalent bonds. HCI + CH, C-O Chymotrypsin-His 57 TPCK Modified enzyme True O False
