the synthesis of glycogen from glucose is anabolic true or false
Question 5 3 pts What is the role of UDP-glucose in glycogen synthesis? O UDP-glucose reacts with a glycogen chain and extends its length by one glucose unit. O UDP-glucose adds a glucose unit to UTP O UDP glucose reacts with ATP to form UTP All of the above. Question 6 3 pts What is the role of "glucagon- and epinephrine-triggered cAMP cascades" in regulating or influencing glycogen synthesis? O These cascades turn on or stimulate glycogen synthesis. O These...
7. Which statement is TRUE of glycogen synthesis and breakdown?---->the answer is A but I need it explained to me. a. Phosphorylation activates the enzyme responsible for breakdown, and inactivates the synthetic enzyme. b. Synthesis is catalyzed by the same enzyme that catalyzes breakdown. c. The glycogen molecule "grows" at its reducing end. d. The immediate product of glycogen breakdown is free glucose. e. Under normal circumstances, glycogen synthesis and glycogen breakdown occur simultaneously and at high rates.
1. (True/false) Because NADPH is mostly involved in anabolic reactions, it has a positive AG • True False 2. Catabolic reactions will have an overall [blank1] Eo versus anabolic reactions that will have an overall [blank2] E. Blank 1 Blank 2 Negative Positive Positive Negative High High Low Low Spontaneous Larger Larger Smaller Smaller Spontaneous 3. In order for an electron carrier to accept electrons, it must have a Positive • High • Low • Negative • Neutral AG 4....
7. (True/false) Because glycolysis produces pyruvate, glycolysis is an anabolic pathway, • True • False 8. Which metabolism is better equipped to support chemotaxis? • Aerobic respiration • Anaerobic respiration • Aerobic chemolithotrophic metabolisms • Gycolysis alone • Tricarboxylic acid cycle alone 9. Comparing a Saccharomyces cerevisiae yeast cell to a Staphylococcus aureus bacterial cell, which one would have the higher S/V ratio? • Staphylococcus aureus • Saccharomyces cerevisiae 10. (True/false) Metabolic pathways represent a predictable linear set of reactions...

Question #8 (10 points) - During fasting, explain what happens for carbohydrate metabolism (glycogen synthesis/breakdown; glucose synthesis/breakdown/insulin & glucagon levels)
1.) ( 3 pts) Glucose monomers are released from glucose by the action of glycogen phosphorylase. Glycogen, + Pi -glucose-1-P + glycogenn-1 The glucose-1-P is then converted into glucose-6-P by the action of phosphoglucomutase. What would be the net ATP and NADH generated during glycolysis using the glucose-1-P generated from the catabolism of the nonreducing end of glycogen into 2 lactates? GIC-6 P 2 pyruvates PFK Net NADHER 4ATPI 2 NADH ATP=3
Tell me whether glucose, glycogen, and pyruvate will be made as a product (enter "+"), reduced as a reactant (enter "-"), or unaltered in production or reduction (enter "0"). If both + and - are true, enter "+-" . With Insulin Glucose Glycogen Pyruvate - With Glucagon Glucose Glycogen Pyruvate With Epinephrine Glucose Glycogen Pyruvate With Cortisol Glucose Glycogen Pyruvate
1. Which of the following is true regarding glycogen metabolism? a. Glycogen synthase is activated by phosporylation. b. Glycogen phosphorylase kinase activates glycogen phosphorylase through phosphorylation. c. The activation of PKA is downstream of insulin signaling in muscle cells. d. Glycogen phosphorylase releases free glucose from the ends of glycogen.
