Glucose can be released from the liver and transported to many other tissues where it is taken up and induces a variety of biological effects. Glucose concentrations in animals range between 40 and 150 mg/100 mL. Based on this information, would you consider glucose to be a hormone? Why or why not? One important characteristic that distinguishes hormones from other chemical messengers is that hormones circulate in extracellular fluids in very low concentrations; that is, at concentrations ranging from picograms (1012 g) to nanograms (109 g) per mL of blood. This is much lower than concentrations of vitamins, minerals, and metabolites, which are present in concentrations of micrograms (106 g) and milligrams (103 g) per mL of blood. based on this is glucose a hormone
GnRH, a peptide hormone produced by hypothalamic neurosecretory cells, and a steroid hormone produced by the ovary, each exert effects on LH-producing cells of the anterior pituitary gland. In general terms, compare and contrast how these hormones act to affect LH release by pituitary cells.
thank you
