EXERCISE 4: Muscle pH 28. If you recall, there are three different metabolic pathways driving ATP production in skeletal muscle that are active at all times. However, the predominant pathway at any given time depends on the speed of the pathway and energy demand of the muscle. a. Which metabolic pathway predominates once creatine phosphate is depleted and before oxidative phosphorylation can occur ? Where does this occur within the cell? b. What is pyruvate converted to when oxygen delivery...
A congenital defect in the liver enzyme fructose-1,6-bisphosphatase may result in metabolic acidosis. Explain.
Create a metabolic pathway map that shows what happens to a glucose molecule that enters a muscle cell and becomes metabolized to lactate (in Oz-depleted muscle). Follow the lactate through the Cori cycle, and show how it ultimately gets converted to a glucose molecule that can once again enter the muscle cell. In addition, show how the glucose may be stored as glycogen, and mobilized from glycogen in both liver and muscle. Also show how pyruvate gets converted to acetyl-CoA...
Which pathways should be stimulated in a muscle cell in resting state? a catabolic pathways because energy charge is low b. anabolic pathways because energy charge is low c. anabolic pathways because energy charge is high Od.catabolic pathways because energy charge is high
Page 1: Question 5 (1 point) ✓ Saved Match the description of cells of liver, muscle, both, or neither. Consider only the gluconeogenesis and glycolysis pathways but ignore whether they have measurable rate under cellular conditions. Assume both cells have constant supplies of pyruvate and glucose and are aerobic. expresses pyruvate carboxykinase has oxaloacetic acid (OAA) as an intermediate expresses glucose 6- phosphatase 1. liver 2. muscle forms net oxaloacetic acid (OAA) 3. both does not express fructose 1,6-bisphosphatase 4....
Describe “hub” molecules acetyl CoA and pyruvate that serve different pathways. Explain metabolic regulation favoring metabolic pathway choices leading to and from hub molecules. Describe how Citric Acid Cycle serves as a “hub “ pathway.
Describe the glucagon and epinephrine effect on the glycogen metabolism in the liver and the muscle. -full points are awarded only when all the signaling transduction pathways are described in details for each hormonal regulation.
Glycolysis and gluconeogenesis are concurrent and complementary metabolic pathways. Which of the following IS NOT TRUE a) glycolysis and gluconeogenesis regulate the availability of glucose in the cell b) all enzymes and intermediates used in glycolysis and gluconeogenesis are the same, glucose, respectively anabolizes acetyl-CoA and pyruvate to glucose. fructose 16P into fructose 6P (final step) in gluconeogenesis uses pathway specific ) glycolysis catabolizes glucose to pyruvate and acetyl-CoA and gluconeogenesis d) the conversion of pyruvate into phosphoenolpyruvate (first step)...
I had this partially wrong too The muscle and liver forms of glycogen phosphorylase respond to different allosteric effectors consistent with the energy status of a given tissue. Select the correct type of regulation with the correct isozyme. AMP ATP Activates liver phosphorylase a Activates liver phosphorylase b Glucose Inhibits liver phosphorylase a Inhibits liver phosphorylase b Glucose 6-phosphate Activates muscle phosphorylase a Activates muscle phosphorylase b Inhibits muscle phosphorylase a | Inhibits muscle phosphorylase b
