1. In the glycolysis pathway (starting with glucose and ending with pyruvate) there are two reactions which convert ADP to ATP. a) Schematically draw the two reactions (substrates, products), and give the names of the enzymes which facilitate these reactions? b) On the basis of the Gibbs free energy of energy-rich phospho-compounds, give a plausible explanation as to why only one of the reactions is reversible? ** Solve for part B only!
