Question

It was noted that cells possess receptors on their surface that allow them to respond to specific stimuli. Many cells in the human body possess receptors that allow them to bind specific

hormones that circulate in the blood. Why do you think these

hormone receptors are important? What would be the effect on

the physiological activities of the body if cells lacked these receptors, or if all cells had the same receptors?

Answer 1

since our body has different cells aggregate as tissue and organs to perform different and specific functions at specific sites. hence every cell needs to have different receptors on the surface to bind to desired hormone , chemical or any other substrate for its vital functioning and processes. if all cells get same receptors on their surface there will be no division of labour among the different cells. hope this little hint helps your question.
thank you, have a nice day.

Answer 2

Ans:These receptors mark specific cells as targets for particular hormones. Without such receptors, cells would not be able to bind a specific hormone and thus would not be able to respond to it. If all cells had the same receptors, hormones would not be able to selectively activate specific target cells. All cells would become potential targets
