A recent study (Prasath, G.S. et al., 2014) found that strawberries contain a compound called fisetin which slows the release of glucose into blood during fasting. This slowing occurs whether the glucose is generated from glycogen hydrolysis or gluconeogenesis. Propose an enzyme that fisetin inhibits and defend your answer. How does the intacellular concentration of citrate affect fructose 1,6-bis phosphatase? [If you cannot remember, try to deduce it.] Describe how this fits into cellular physiology. Describe a situation in gluconeogenesis where having a cytoplasmic and mitochondrial isoenzyme that can catalyze the same reaction provides a benefit. Can the energy in consumed ethanol be stored in glycogen? Explain.
