Suppose that the circulating concentration of hor-mone is 10–10 M and the Kd for binding to its receptor is 10–8M. What fraction of the receptors will have hormone bound?If a meaningful physiological response occurs when 50% ofthe receptors have bound a hormone molecule, how muchwill the concentration of hormone have to rise to elicit aresponse? The fraction of receptors (R) bound to hormone(H) to form a receptor–hormone complex (R–H) is [R–H]/([R] + [R–H]) = [R–H]/[R]TOT = [H]/([H] + Kd).
A certain peptide hormone is produced in the anterior pituitary gland located at the base of the mammalian brain. The hormone targets specific cells in many parts of the body. Which of the following best explains a possible mechanism that would allow the hormone to reach all of the target cells in the body? A B с D The hormone diffuses into target cells adjacent to the anterior pituitary gland and dif- fuses through their cell membrane. The hormone moves through plasmodesmata between cells until it has reached all cells with the correct intracellular binding sites. The hormone interacts with neurons at the base of the brain and directs signals to the target cells through the neuronal network. The hormone is released into the bloodstream, where it is transported to all cells with the correct receptors.
How could you determine whether a hormone-mediated response hasresulted from the intracellular mediator mechanism or the nuclearreceptor mechanism?
Master endocrine gland – all are proteins or peptides, act through second-messenger systems, and are regulated by hormonal stimuli and in most cases negative feedback?
Which is NOT true of steroid hormones? O They can not diffuse through the lipid bilayer of a membrane. They include hormones like testosterone and estrogen. O They bind to receptor proteins inside target cells. When they bind with receptors, specific genes are activated resulting in cell char ↑ The mineralocorticoid called aldosterone is produced by the adrenal cortex and it stimulates the reabsorption of sodium ions in the nephrons renal cortex and it increases blood pressure adrenal medulla and it increases blood glucose levels renal medulla and it stimulates the reabsorption of sodium ions in the nephrons C 31 6 O

Explain how the chemical nature of the plasma membrane acts on the two chemical categories of hormones, and thus the type of response each hormone can induce in a target cell. Be sure to thoroughly describe the two types of cellular responses.
Which type of hormone receptor—plasma membrane bound or intracellular—would be expected to provide the most long-lived response to hormone binding and why?
