Introduction:
Hormones are chemical messengers secreted by the endocrine glands or neurosecretory cells into the extracellular fluids. The secreted hormones reach the target cells through the bloodstream and they stimulate response of other tissues or cells. Hormones bind only to specific cells based on their corresponding receptors present on cells. Hormones act through chemical signals. They regulate growth, development, blood pressure,

Justify the answer schematically.arrow_forwardWhy do you think the speed of action for glucocorticoids is different to adrenaline and nor-adrenaline?arrow_forwardDescribe the principal functions of the two major groups of adreno-cortical steroids, the glucocorticoids, and the mineralocorticoids. To what extent do these names provide clues to their function?arrow_forward
- Predict the biochemical and whole body effects of an overdose of insulinarrow_forwardIn experiments to test the appetite-suppressing eff ects of PYY3–36, why must the hormone be administered intravenously rather than orally?arrow_forwardWhat is the ultimate response of the cell to the insulin pathway?arrow_forward
- Why would a cause of hyperinsulinism be hypoglycemia? Don’t lower levels of blood glucose inhibit of insulin rather than produce large amounts of it to result in hyperinsulinism?arrow_forwardOutline the signal transduction associated with epinephrine’s induction of the breakdown of glycogen.arrow_forward
