WGU BioChem C785 Carbohydrates and ATP Exam Questions with COMPLETE SOLUTION During gluconeogenesis, how many ATP molecules are consumed for each glucose molecule produced? 4 2 1 6 - ✔✔6 Whic... h molecule signals the liver to release glucose by breaking down glycogen? ATP Eicosanoids Glucagon Insulin - ✔✔glucagon High levels of glucose stimulate insulin which increases glycogen formation. Which molecule is regenerated with the production of lactate during anaerobic metabolism? FAD NAD+ FADH2NADH - ✔✔NAD+ During aerobic metabolism, acetyl-CoA is produced from which molecule? Glycerol Oxaloacetate Pyruvate Lactate - ✔✔Pyruvate Acetyl-COA is produced from the breakdown of pyruvate after glycolysis. Why would a marathon runner consume a large meal full of complex carbohydrates the night before her run? To replenish cellular stores of DNA To replenish cellular stores of protein To replenish cellular stores of ketone bodies To replenish cellular stores of glycogen - ✔✔To replenish cellular stores of glycogen Why must red blood cells rely solely on glycolysis to make ATP? Red blood cells lack mitochondria.Red blood cells lack cytoplasm. Red blood cells absorb too much oxygen. Red blood cells cannot absorb oxygen. - ✔✔Red blood cells lack mitochondria. Red blood cells transport oxygen by hemoglobin but lack mitochondria. What are advanced glycation end products (AGEs)? Glucose molecules linked to DNA or RNA without the need for enzymes The end products of glycolysis The end products of glycogenolysis Glucose molecules linked to lipids or proteins without the need for enzymes - ✔✔Glucose molecules linked to lipids or proteins without the need for enzymes AGEs are glucose molecules linked to lipids and proteins. Why are blood glucose levels high in patients with unmanaged Diabetes Mellitus? Cells move too many GLUT4 transporters to their cell membranes. Ketogenesis is stimulated in the liver. Cells do not move enough GLUT4 transporters to their cell membranes.Ketogenesis is suppressed in the liver. - ✔✔Cells do not move enough GLUT4 transporters to their cell membranes. Cells that do not move enough GLUT4 transporters to the cell membranes will cause blood glucose levels to be high. What kind of molecule is glycogen? A complex carbohydrate A triglyceride A protein A simple carbohydrate - ✔✔A complex carbohydrate What happens in the liver cells when they respond to insulin? GLUT4 transporters move to the surface of the cell. Gluconeogenesis is increased. Beta-oxidation of fatty acids is increased. Glycogenolysis is increased. - ✔✔GLUT4 transporters move to the surface of the cell [Show More]
