Which of the following statements about fructose 2,6-bisphosphate (F2,6BP) is NOT true?

It is made by PFK1.
It is broken down by FBPase-2.
Insulin stimulates its production.
It favors glycolysis by activating phosphofructokinase (PFK).

Inhibin
Glucagon
Insulin
Epinephrine

Insulin
Androgen
Inhibin
Glucagon
Hepcidin

Which of the following is true of fructose-2,6-bisphosphate?

It allosterically affects the activities of phosphofructokinase-1 (PFK-1) and fructose-1,6-bisphosphatase enzymes.
It allosterically affects the activities of the adenyl cyclase enzyme.
It allosterically affects the function of insulin hormones.
It stimulates the production of glucagon and epinephrine hormones.
It stimulates the production of insulin by the pancreas.

Which of the following statements is NOT true regarding the hormonal regulation of glucose in the body?

Insulin and epinephrine hormones directly bind to the catalytic sites of the FBPase enzyme and regulate the simultaneous working of gluconeogenesis and glycolysis.
The enzyme protein kinase A gets activated by the hormones epinephrine and glucagon.
In response to the high levels of insulin, the G-protein gets inactivated, and then the insulin-stimulated phosphatase enzyme converts FBPase to PFK-2 form and starts the glycolysis pathway.
The activated FBPase-2 activates gluconeogenesis by synthesis of fructose-6-phosphate from fructose-2,6-bisphosphate.
The activated protein kinase A enzyme causes the phosphorylation of PFK-2 and activates the FBPase-2 activity.

Which of the following is NOT an endocrine gland?
