These are for my final grade thank you in advance and please

These are for my final grade, thank you in advance and please just focus on answering the question. Thank you so much.

1) Which hormone type –steroid and nonsteroid-would be best suited for a fast, large-scale, but quickly declining response?

2) Why are prostaglandins referred to as tissue hormones?

3) If a person is dehydrated, how would the level of antidiuretic hormone (ADH) secreted by the posterior pituitary gland change?

Solution

1) Which hormone type –steroid and nonsteroid-would be best suited for a fast, large-scale, but quickly declining response?

Answer: Nonsteroid hormones are going to act from milliseconds to minutes times on the cell surface receptors so that triggering of downstream events within the cell. For example, adrenaline and nor-adrenaline are the neurotransmitters and hormones, which act in a short period followed by quickly declining response. Steroid hormones often take longer to produce downstream events because they act on the \"nuclear receptors\" after diffusing through plasma membrane

Que-2: Prostaglandins are often referred to as tissue hormones because they are the metabolites of arachidonic acid due to inflammatory mediation
