Gluconeogenesis takes place during intense exercise, which seems counterintuitive. Why would an organism synthesize glucose and at the same time use glucose to generate energy?
It is noticed that when a strain of mice exercises, their blood glucose drops to very low levels. Which of the following can explain this situation?
a) These mice do not make enough insulin
b) these mice lack insulin receptors on their cells
c)these mice lack glucagon
d) these mice cannot synthesize glycogen from glucose

On a low-carb diet, keto acids from glucogenic amino acids will be used to synthesize glucose. Glucose is metabolized in the mitochondria of mature red blood cells.

- Epinephrine stimulates glycogen breakdown by activating glycogen phosphorylase. However, in the research lab, no glycogen breakdown occurred when epinephrine was added to a test tube containing the enzyme and its substrate, glycogen. Explain why glycogen phosphorylase could be activated by epinephrine only when the hormone was added to intact cells in a solution.arrow_forwardJohn was repeating George Palade's pulse and chase experiment to trace insulin secretion pathway within cells. When he observed his samples under the electron microscope, he saw the ³H]-leucine labelling all over the cells, which indicates that he made some mistakes in carrying out the experiment.

- Why does the lack of glucose 6-phosphatase activity in the brain and muscle make good physiological sense? Glucose 6-phosphatase allows cells to trap glucose in the cell; however, these tissues primarily rely on noncarbohydrate energy sources. Glucose 6-phosphatase allows cells to generate glucose through gluconeogenesis; however, gluconeogenesis only takes place in the liver. Glucose 6-phosphatase allows cells to release glucose into the blood; however, these tissues should never release glucose. Glucose 6-phosphatase provides glucose 6-phosphate for glycogen synthesis; however, these tissues do not need glycogen.arrow_forwardhow do cells keep cytoplasmic glucose concentration low?arrow_forwardwhat linkage does glycogen synthase catalyzes?arrow_forward
