To be considered a target cell for a particular hormone, a cell must ….     a)  be experiencing a disruption in homeostasis.   b)  be the same cell type as the one that produced the hormone.   c)  be capable of producing that hormone.   d)  be located relatively close to the cells that produced the hormone.   e)  have receptors that recognize and bind to the hormone.

Which of the following observations can be explained by the properties of hormone receptors? a) A certain tissue can react to more than one hormone b) A certain hormone affects only a specific tissue, not all tissues c) Some tissues react very quickly to a certain hormone, other tissues take many hours to react to the same hormone

A steroid hormone approaches its target cell. Which of the following happens first?  a)The hormone enters the nucleus.  b)The hormone passes through the cell membrane.  c)The hormone and its receptor bind to the cell's DNA. d) The hormone and its receptor enter the cell's nucleus.

26) Which of the following hormones is categorized incorrectly? A) Testosterone-steroid B) Insulin-peptide.

43.

The _____ effects of a hormone occur prenatally and/or shortly after birth. They affect the structure of the body, and they are permanent and non-reversible (they do not disappear when the hormone stops circulating).   A) activating   B) orienting   C) organizing

The effect of hormones on their target is always a linear relationship of its concentration. a) This is incorrect. There is no measurable relationship between the concentration of a hormone and its effect on the target. b) This is true. Higher concentration always leads to stronger effect on their targets. c) This is incorrect. Some hormones have non-linear dose effects. d) This is true. Lower concentration always leads to weaker effects on their targets.

Which of the following types of molecules can be a hormone? a) Phospholipids b) Fatty acid derivatives c) Proteins d) Nucleic acid derivatives e) Peptides

2. State which hormone is probably responsible for each physiological phenomenon described below and explain why. a) Blood glucose levels remained constant even though someone went 20 hours without eating or drinking. b) Heart rate and breathing rate increase when someone is awoken by a loud noise in the middle of the night. c) A grown man's jaw and forehead become thick and deformed.

Which of the following is not a true statement? A.) steroid and thyroid hormone signaling would be impaired if the plasma level of carrier proteins is not optimal. B.) Steroid and thyroid hormone-receptor complexes form dimers when they bind to the hormone-response elements on DNA C.) Epinephrine uses the adenylate cyclase and the phospholipase C second messenger systems D.) signaling by a peptide hormone would be impaired if a second messenger system is not functional in the target cell E.) signaling by a steroid hormone would be hindered if the adenylated cyclase second messenger system is not functional in the target cell.
