Assuming each glycosidic linkage can be broken down completely and the resulting products are fed through glycolytic metabolism. a) If this molecule was in your muscles, how many molecules of ATP would it generate through fermentation? how many molecules of lactate? b) If the same molecule was in your liver, but was instead fueling glycolysis in your brain, how many molecules of ATP would it generate for the brain through glycolysis? c) The lactate produced in (a) is then transported back to the liver from your muscles. There, it can be used to drive glucose synthesis (known as the Cori cycle). Assume all glucose from this lactate is then re-incorporated into newly synthesized glycogen. List the steps needed for this transformation in the liver and the amount of ATP equivalents it will consume (going from lactate). Also, identify a signaling pathway that would trigger its incorporation into new glycogen, instead of being…arrow_forwardFor each of the four possibilities listed below (a through d), only one answer is correct and the others are false. Identify the correct statement and explain why the others are false. In your answer, write CORRECT next to the statement that you think is true, and ONLY for the ones that you think are false, explain what is wrong with the statement . When glucose reacts with ATP to form glucose-6-phosphate (as shown on the figure below): 1. The synthesis of glucose-6-phosphate is exergonic 2. ADP is at a higher energy level than ATP 3. Glucose-6-phosphate is at a higher energy level than glucose 4. Because ATP donates a phosphate to glucose, this is not a coupled reactionarrow_forward
