Chemistry Most of the reactions in gluconeogenesis are the simple reversal of the ‘forward’ reactions used in glycolysis. However, formation of PEP in gluconeogenesis from pyruvate by pyruvate kinase is not feasible because the DG of this reaction is too unfavourable. Describe the source(s) of the energy used in gluconeogenesis to drive the production of PEP.

Arrange the balanced biochemical equations for all the reactions in the payoff phase of glycolysis and the conversion of pyruvate to lactate.
Write balanced biochemical equations for all the reactions in the catabolism of glucose to two molecules of pyruvate (the preparatory & payoff phase of glycolysis), including the standard free-energy change ΔG for each reaction. Then write the overall or net equation of glycolysis, with the net standard free-energy change when one molecule of glucose is converted into 2 molecules of pyruvate.
H. OH co co2 но H co, 1-isopropylmalate 2-isopropylmalate Biosynthesis of leucine involves conversion of 1-isopropyimalate to 2-isopropylmalate (see above). This proceeds in four steps under basic enzymic catalysis via an isolable compound produced in step 2. Write a detailed mechanism for this conversion. Then, draw the intermediate compound) produced in step 2. • You do not have to consider stereochemistry. • Draw uninvolved carboxyl groups in the anionic state, and enolates as carbanions.

Regulatory enzymes are crucial for the proper functioning and coordination of glycolysis and gluconeogenesis. As a general rule, regulatory enzymes catalyze reactions that are far from equilibrium. Why does this make good biochemical sense?
Creatine is a popular dietary supplement. What is the biochemical rationale for the use of creatine? It would serve as an electron donor to support reductive biosyntheses required to sustain cellular function. It would promote the movement of ions through ion channels and thus power the synthesis of ATP during exercise. It would be converted into creatine phosphate and thus serve as a rapid means of replenishing ATP during muscle contraction. O It would directly serve as an electron carrier to support the oxidation of fuel molecules and thus energy production. What type of exercise would benefit most from creatine supplementation? O a long-distance run a leisurely walk yoga O sprinting
