1) How is the TCA cycle regulated? a) Draw the TCA diagram that fills in all possible regulation points.
Which of the following activate glycogen synthesis? A. Phosphorylation of glycogen synthase kinase 3 B. Activation of protein kinase A (PKA) C. Both A and B D. Neither A nor B Assuming that glucokinase is completely inhibited, which of the following statements is correct? Glycolysis reactions beyond glucose-6-phosphate in the liver would be impossible to take place The Cori cycle would be blocked Both A and B Neither A nor B
Falling energy levels increase the cellular AMP/ATP ratio, priming AMPK for activation by the liver kinase B1 (LKB1). AMPK phosphorylates multiple targets with the cumulative effect of blocking anabolic reactions and stimulating energy-generating catabolic pathways. Group of answer choices True False
Which of these is associated with production of ATP during glycolysis? (Select all that apply) a) Conversion of 1,3-BPG to 3PG b) Conversion of 1,3-BPG to 2,3-BPG c) Conversion of PEP to pyruvate d) Conversion of 2,3-BPG to 2PG e) Phosphorylation of glucose
The synthesis and degradation of glycogen in muscle is not a futile (ATP-hydrolyzing)cycle because:A. glycogen synthase and phosphorylase are simultaneously activatedB. cyclic AMP activates adenylate kinase. C. when glycogen synthase is inactivated, phosphorylase is simultaneously activated. D. glycogen binds Mg2+, thereby lowering the concentration of MgATP2-
If PFK is activated in the liver, which of the following statements would be false? a) There are high levels of fructose 2,6 bisphosphate b) PFK is in the R-state c) Glycolysis would be activated d) AMP levels are low e) Gluconeogenesis is inhibited in the liver
Type VI glycogen storage disease (Hers disease) is a rare metabolic disorder caused by lack of phosphorylase kinase in the liver. In your own words describe how each of the following metabolic parameters/observations will be affected/unaffected in a person with Type VI GSD (a) Blood glucose levels, after fasting (e.g. before breakfast). (b) Blood glucose levels, immediately following a meal. (c) Storage of glycogen in the liver and muscles. (d) ATP concentration in the muscles
1.a. Given what you know about glycolysis and gluconeogenesis, does it make sense that insulin activates PDH phosphatase? Why? b.How do vitamins increase to the breadth of chemical reactions available within a biological system?
In muscle tissue, the rate of conversion of glycogen to glucose 6-phosphate is determined by the ratio of phosphorylase a (active) to phosphorylase b (less active). Determine what happens to the rate of glycogen breakdown if a muscle preparation containing glycogen phosphorylase is treated with: (a) phosphorylase kinase and ATP; (b) PP1; (c) epinephrine
Digoxin, a toxin derived from the foxglove (shown), can be used to treat heart disorders such as atrial fibrillation. Digoxin’s mechanism of action is to inhibit the Na+/K+ ATPase. Which of the following is the most likely side effect of Digoxin treatment? Failure to transport glucose into cells during an extended fast Failure to transport glucose into cells after after eating a large meal Enhanced response of muscle cells to Acetylcholine Failure to transport Cl- out of the cell using direct active transport
