Gluconeogenesis in humans involves many of theenzymes of glycolysis working in a reversedirection, but utilizes four unique enzymes. (a)Draw these four reactions at pH 7, indicating thereactants and products, and the full name of theenzyme. You are required to draw the structuresof the products and reactants for the first tworeactions in gluconeogenesis and their full namesbut only provide the full names on the remainingtwo reactions. You do not have to draw thestructures of any cofactors just use theirabbreviations.

When the reaction below reaches equilibrium, does the equilibrium lie on the left or the right side? Briefly explain. ClO– + CH3CO2H ⇌ HClO + CH3CO2– When the terminal phosphate is cleaved from the adenosine triphosphate molecule, the products are adenosine diphosphate and inorganic phosphate, ATP + H2O ––> ADP + Pi, where Pi stands for the various forms of phosphate that exist at the pH of the particular solution. If the total concentration of Pi is 2.5 x 10–2M, what are the concentrations of the predominant forms of phosphate that exist at pH 7.4?
