When the blood glucose concentration is low, the pancreas secretes glucagon to signal the liver to produce glucose and glucose-1-phosphate. Which metabolic steps are involved in this biosignaling pathway

See below (Correct I and IV)

Explanation:

Inactivation of glycogen synthase via phosphorylation by protein kinase A

Activation of glycogen synthase via phosphorylation by protein kinase A

Activation of phosphofructokinase-2 via phosphorylation by protein kinase A

Activation of fructose-2,6-bisphosphatase via phosphorylation by protein kinase A

Activation of phosphofructokinase-1 by fructose-2,6-bisphosphate

Inhibition of fructose-1,6-bisphosphatase by fructose-2,6-bisphosphate

Inactivation of pyruvate kinase via phosphorylation by protein kinase A

I and IV

I, III, V, VI, and VII

I, IV, and VII

Correct (b) I and IV

Glycogenolysis: It is the process by which glycogen stored in liver and muscle cells, break down to form glucose.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

i think the answer is b.
