In the endocrine system, it asks, "describe the two major mechanisms by which hormones bring about their effect on their target tissues?"I was thinking it was polar and non polar soluble because that's the major component when it comes to how cells react to their hormones, it determines how fast the reaction time.

What are the definitions of the phrases chemical messenger, target tissue, and hormone receptor?

Why is it important for hormones to act at low concentrations and be degraded quickly?

Please give the answers only

What characteristics of a chemical substance define it as a hormone, and how can hormones attain cell type specificity?

Identify the incorrect statement: O A. Steroid hormones, such as testosterone, are derived from cholesterol and regulate cell function by influencing transcription. O B. Melatonin is a hydrophobic steroid hormone synthesized by the pineal gland It regulates the circadian rhythm of the cell OC. Catecholamines are hydrophilic hormones synthesized from tyrosine. Therefore, membranes are barriers to them, and their receptors need to be on the extracellular surface. O D. Antidiuretic hormone is a peptide hormone that regulates fluid balance in the body O E. Thyroid hormone is a hydrophobic tyrosine derived hormone that regulates the metabolism,

How could you determine whether a hormone-mediated response hasresulted from the intracellular mediator mechanism or the nuclearreceptor mechanism?

Which of the following statements are false regarding the endocrine (hormones) in comparison to the paracrine system? (there may be more than one answer) Hormones are less stable than paracrine signals Hormones have a lower affinity for their receptors than paracrine signals Hormones are produced in a greater quantity than are paracrine signals Hormones are produced by most cell types; paracrine signals are only produced as a response to an insult (wound or infection). Hormones are produced from cells at a greater distance to their response elements than paracrine signaling.

Which of the following are ways in which hormones exert their effects?   - by controlling the rates of enzymatic reactions - by controlling changes in gene transcription - by activating postsynaptic receptors and generating EPSPs in hypothalamic neurons - by controlling the transport of ions across a cell membrane

Why are eicosanoids often referred to as "local hormones"?
