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.

A hydrophilic peptide hormone is produced in the anterior pituitary gland located at the base of the brain. The hormone targets specific cells in many parts of the body. Which of the following best explains a possible mechanism that would enable the hormone to efficiently reach all the target cells in the body? A. Restate the question and record the right answer. B. Why is this the correct answer?
Choose an endocrine gland of your interest.Imagine a human being lacking the saidendocrine gland. Predict what might happen tothe individual. How will the absence of theendocrine gland affect the homeostatic events,growth, development, differentiation andmultiplication of the body tissues?
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).
Which of the following occurs by active transport A)transport of Na+ from region of higher concentration through a region of lower concentration through a channel B) simple didfussion of a steroid hormone through the plasma memebrane C) Faciltated diffusion of Cl- down it's concentration gradient D) Transport of K+ across the plasma memebrane using cellular ATP
Given these events:(1) The α subunit of a G protein interacts with Ca2+channels.(2) Calcium ions diffuse into the cell.(3) The α subunit of a G protein is activated.Choose the arrangement that lists the events in the order they occurafter a hormone binds to a receptor on a smooth muscle cell.a. 1,2,3 c. 2,1,3 e. 3,2,1b. 1,3,2 d. 3,1,2
The pituitary gland starts sending out hormones into the blood stream to initiate puberty, as is seen in the image. Which of the following statements best describes what the image is showing about how those hormones are received by the organs associated with puberty? The hormones circulate all over the body and act upon every cell. The hormones are dispersed to a specific area of the body and bind to target cells there. The hormones are dispersed and received only by cells in range of the signal before they degrade. The hormones circulate all over the body and bind to specific receptors that only target cells possess.
Which of these is not a means by which hormones are eliminatedfrom the circulatory system?a. excreted into urine or bileb. bound to binding proteinsc. enzymatically degraded in the blood (metabolism)d. actively transported into cellse. conjugated with sulfate or glucuronic acid
Which one of the following hormones does not have intracellular receptors? a. Estrogens b. Cortisol c. Insulin d. Epinephrine e. T3 Gs proteins serve as transducers in the action of: a. Testosterone b. PRL c. GH d. TSH
Which of these homeostatic mechanisms in the body are examplesof positive feedback, and which are examples of negative feedback?Why?a. The adrenal glands produce epinephrine in response to a hormone produced by the pituitary gland in times of stress; the pituitary gland senses the epinephrine in the blood and stopsproducing the hormone.b. As the bladder fills with urine, pressure sensors send messagesto the brain with increasing frequency, signaling that the bladdermust be emptied. The more the bladder fills, the more messagesare sent.c. When you drink an excess of water, specialized cells in yourbrain, as well as stretch receptors in your heart, detect theincrease in blood volume. Both signals are transmitted to thekidneys, which increase the production of urine.
Figure 16.14 Goiter, a disease caused by iodine deficiency, results in the inability of the thyroid gland to form T3 and T4 .

Hypothyroidism, resulting in weight gain, cold sensitivity, and reduced mental activity. b. Hyperthyroidism, resulting in weight loss, profuse sweating and increased heart rate. C. Hyperthyroidism, resulting in weight gain, cold sensitivity, and reduced mental activity. d. Hypothyroidism, resulting in weight loss, profuse sweating and increased heart rate.
