Which of the following statements are True? Multiple answers: Multiple answers are accepted for this question Select one or more answers and submit. For keyboard navigation. SHOW MORE V If [1-14C) Ribose-S-phosphate is incubated with a mixture of purified transketolase- transaldolase-phosphopentose isomerase-phosphopentose epimerase and glyceraldehyde-3-phosphate Fructose-6-phosphate will be labeled in the 1 and 3 positions. a Starting with Glucose 6-phosphate labelled in carbon number 1 with radioactive carbon and taken through the axidative phase of the Pentose Phosphate Pathway and the first transaldolase reaction gives rise to a 7-carbon intermediate labeled with radioactive carbon in carbon number 1. Avidin is a protein that binds extremely tight to biotin. So avidin would be a potent inhibitor of Acetyl CoA Carboxylase. The two electrons derived from the a-Ketoglutarate Dehydrogenase complex come from dihydrolipoic acid. In Fatty Acid synthesis carbon atoms 15 and 16 of Palmitic…

CHOOSE THE CORRECT LETTER There are four enzymes of gluconeogenesis that circumvent the irreversible steps in glycolysis. When starting with the substrattpyruvate, they are:A. Pyruvate carboxylase, phosphoenolpyruvate carboxykinase, fructose 1,6-bisphosphatase, and hexokinaseB. Pyruvate carboxylase, phosphoenolpyruvate carboxykinase, fructose 1,6-bisphosphatase, and glucose-6-phosphataseC. Glycerol kinase, glycerol 3-phosphate dehydrogenase, fructose 2,6-bisphosphatase, and glucose 6-phosphataseD. Hexokinase, phosphofructokinase, phosphofructokinase and pyruvate kinase
If the brain needs glucose, then gluconeogenesis stops after reaction (9, 8, 10, 2) because (phosphoenolpyruvate, glucose, glucose-6-phosphaet, fructose-6-phosphate) can be exported from the hepatocyte using a transporter.
Which of the following is true for role of glucose-6-phosphate in the regulation of carbohydrate metabolism? -Glucose-6-phosphate allosterically activates glycogen phosphorylase -Glucose-6-phosphate allosterically inhibits glycogen synthase -Glucose-6-phosphate allosterically inhibits hexokinase kinase -None of the above are correct For a reaction A + B --> C + D, [A] is 0.1M, [B] is 0.1M, [C] is 0.1M, and [D] is 0.1M. which of thefollowing is true? -It is a near-equilibrium reaction -The standard free energy change equals 0.00 -The equilibrium constant equals 1.00 -Mass action ratio equals 1.00
The glycolytic pathway is regulated by a number of key enzymes. Describe the various substrates and hormones that act on these enzymatic steps and the type of regulation (e.g. allosteric etc.).
At normal to low blood glucose concentrations (1.e., roughly 110 mg/dl or less), the enzyme that is responsible for sequestering or trapping glucose within cells is which of the following enzymes? O hexokinase O glycogen synthase O glucose-6-phosphatase O glucokinase
Indicate what will happen (increase, decrease or no effect) to the activity of enzyme or rate of the metabolic pathway given the following conditions: 1. epinephrine to the activity of glycogen synthase 2. high [2-carboxyarabinitol-1-phosphate] to the carboxylase activity of RuBisCO
What glycolytic intermediate is fructose converted to in the muscle, such that it can be utilized in glycolysis? Glucose 6-phosphate Fructose 6-phosphate Glyceraldehyde 3-phosphate Dihydroxyacetone phosphate
phosphofructokinase reaction of Fructose-2,6-bisphosphate is a regulator of both glycolysis and gluconeogenesis for the glycolysis and the fructose-1,6-bisphosphatase reaction of gluconeogenesis. In turn, the concentration of fructose-2,6-bisphosphate is regulated by many hormones, second messengers, and enzymes. Classify each condition according to its effect on glycolysis and gluconeogenesis Activates glycolysis and inhibits gluconeogenesis Activates gluconeogenesis and inhibits glycolysis Answer Bank activation of PFK-2 increased glucagon levels increased levels of cAMP increased levels of fructose-2,6-bisphosphate activation of fructose-2,6-bisphosphatase (FBPase-2)
