Two hikers get lost in the woods, they have not brought any snacks or water with them. as time passes their insulin to glucagon ratio decreases 24 hours into their fast you would expect the enzymatic activity of both and to be elevated n the liver.

a. glycogen synthase and carnitine palmitoyl-transferase i
b. pep carboxykinase and pyruvate kinase
c. glutamine synthase and phosphofructokinase 2 (pfk2)
d. glutaminase and carbamoyl phosphate synthetase 1

PEP carboxykinase and pyruvate kinase

Explanation:

as the body needs more amount of glucose as the time passes, so PEP carboxykinase level will increase to convert the fats and proteins in to the glucose to fulfill the body needs. the function of  PEP carboxykinase is to convert the fat and proteins to glucose during gluconeogenesis process when there is requirement of body in low diet conditions.

Pyruvate kinase level will increase as the phosphorylation of PK will cause the inhibition and recycling of enzyme called  phosphoenolpyruvate. this will results in the increase synthesis of glucose.

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
