The hormone epinephrine causes opposite effects in two populations of target cells because . See Concept 45.1 (Page 999) View Available Hint(s) The hormone epinephrine causes opposite effects in two populations of target cells because . See Concept 45.1 (Page 999) the chemical form of epinephrine released by neurons is different from the epinephrine released by endocrine cells epinephrine crosses the membrane on one set of target cells but binds to membrane-bound receptors in the other set of target cells epinephrine activates biochemical pathways in one set of target cells but works only by changing gene expression in the other set of target cells epinephrine can only reach target cells in adipose tissue, as it is fat-soluble each set of target cells has different receptor-transduction mechanisms

Answers

1. False
2. True
3.True
4. B
5. C
6. True
7. B

The correct answer is option b.

Explanation:

Aldosterone is a mineralocorticoid, that is, a steroidal hormone that plays important role in regulating blood pressure as well as the levels of sodium and potassium in the plasma.

It is released from adrenal gland. Being steroidal in nature, it is capable of bypassing plasma membrane easily.

However, its receptors are present inside the cell, that is, in cytoplasm.

These receptors are expressed or present only in the target cells due to which this hormone produces its effects only in the target cells.

Once bound to intracellular receptor, the cell signalling results in alterations in gene expression which produces the desired effects.

.3.The hormone is released into the bloodstream where it can be transported to all cells with the correct receptors.

Explanation:

The mode of transportation of hormones is bloodstream.They used the  medium  to reach the target cells.This makes the  hormonal effects relatively slower compare to eletrical transmission in the Nervous system.

100% CORRECT ANSWERS

Question 1

The endocrine system

is responsible for hormone production and directing long-term changes in the body  

Question 2

Generally, the actions of hormones

cause changes in the actions of the body's cells  

are slower to react than the nervous system  

tend to be more widespread than actions of the nervous system  

All of the above.  

Question 3

The pancreatic hormone that causes blood sugar levels to decrease is

insulin  

Question 4

The pancreatic hormone that causes blood sugar levels to rise is

glucagon  

Question 5

Which major group of hormones is made from cholesterol?

steroid hormones

Question 6

(COULD NOT FIND ANSWER)

Question 7

Endocrine organs can be controlled by

hormones from other endocrine glands  

releasing hormones from the hypothalamus  

direct neural stimulation  

All of the above.  

Question 8

Which of the following organs has both endocrine and exocrine functions?  

pancreas  

Question 9

Alcoholic beverages cause excessive production of urine through blocking the action of  

ADH  

Question 10

In Type II Diabetes, insulin is generally produced at normal levels, but the target cells are less sensitive to the effects of that insulin. You could infer that

the target cells may lack enough insulin receptors

d) Enhance the drug's distribution to non-target cells in the patient

D

Explanation:

Similarity of the drug molecule to other molecules transported by the target cells.

option B) intracellular receptors are present only in target cells.

Explanation:

The cell membrane or plasma membrane is composed of phospholipids and thus hydrophobic in nature, this allows the lipid soluble signaling molecules to cross the membrane. The cell membrane of all cells consist of phospholipids thus hydrophobicity of each cell membrane allows lipid soluble signaling molecules to pass through the plasma membrane. The testosterone cross the membranes of all cells but affect only target cells because of intracellular recepters that are located in target cell. The binding of signaling molecules to recepter generates a response. Thus, option B is correct.

The answer is D: The hormone is released into the bloodstream where it can be transported to all cells with the correct receptors.

The correct answer is b
