Conversion of pyruvate to glucose by reversal of glycolysis has a ?Go’ of +84 kJ/mol, whereas gluconeogenesis occurs with a ?Go’ of ?38 kJ/mol. Where does the energy come from that drives gluconeogenesis? Show the three enzyme reactions where this energy is consumed.

Which of the following about glycolysis is correct? a. each glucose is split into 4 pyruvate molecule b. glucose is the only monosaccharide that can be broken down by glycolysis c. NADH is formed from NAD+ d. Energy is NOT needed to initiate glycolysis

In the first by-pass step of gluconeogenesis, the conversion of pyruvate to phosphoenolpyruvate, pyruvate is carboxylated by pyruvate carboxylase to oxaloacetate, which is subsequently decarboxylated by PEP carboxykinase to yield phosphoenolpyruvate. Explain using thermodynamic terms why this by-pass step is necessary. Why couldn't the glycolytic enzyme responsible for interconverting phosphoenolpyruvate and pyruvate also participate in the gluconeogenesis pathway?

In glycolysis, the conversion from pyruvate to acetyl CoA is irreversible, but I found that during the synthesis of FA, acetyl CoA can be synthesized to citrate -> OAA -> Malate ->pyruvate when Citric acid shuttle, why we cannot say that pyruvate can turn back to acetyl CoA?

Compare the ATP yield of three glucose molecules that enter glycolysis and are converted to pyruvate with that of three glucose molecules that proceed through the pentose phosphate pathway such that their carbon skeletons (as two F6P and one GAP) reenter glycolysis and are metabolized to pyruvate. Indicate the steps where ATP was used or produced and the overall ATP totals.

1. What is the major byproduct of anaerobic glycolysis: ATP, NADH, lactate, or pyruvate? 2. Glucose is retained in cells because it is phosphorylated, degraded, bound, or modified by amylase? 3. Is the final product of glycolysis acetyl CoA, glucose, lactate, or pyruvate? 4. Does Glycolysis generate no ATP, 1 ATP, 2 ATPs, or NADH? 5. Are DNA ends replicated by DNA polymerase, telomerase, RNA polymerase, or primase?

1.) In the first step of glycolysis, the cell SPENDS an ATP and phosphorylates glucose as soon as it enters the cell. Why does the cell do this? Give two reasons! 2.) Speculate on why glycolysis, which is the beginning point of many catabolic pathways does not require oxygen.
