Each of the following statements concerning the hormone atrial natriuretic peptide are true, except one, identify the exception
Mariana [72]

Answer:

The correct answer is E.

Explanation:

The main function of <u>atrial natriuretic peptide</u> (ANP) is to reduce extracellular fluid volume by increasing renal sodium excretion.

<u>Aldosterone</u> is a steroid hormone, produced by the adrenal cortex, that is part of the renin-angiotensin-aldosterone system which helps to maintain blood pressure. Aldosterone increases reabsorption of sodium and potassium excretion, and as a result an increase in extracellular fluid volume and in blood pressure.  

In conclusion, <em>ANP reduces aldosterone secretion.</em>

Some hormones act through cell membrane receptors that stimulate adenylate cyclase activity and production of _____________.
Tresset [83]

Answer:

The answer to fill in the blank in this question: Some hormones act through cell membrane receptors that stimulate adenylate cyclase activity and production of:____, would be: cAMP.

Explanation:

In the process of hormonal regulation of cells there are two ways in which this can happen: direct activation of DNA inside a cell through steroid hormones, who do not need any kind of mediators to enter the cytoplasm of a cell and activate its genetic material, or indirect activation, which is the common way for non-steroidal hormones, such as epinephrine. In this second scenario a hormone will reach the cell and lock onto a receptor on the plasma membrane. The effect is that a G-protein, which is adjacent to the receptor, activates the second-messenger system, meaning that the activity the hormone came to initiate, will depend on these mediators. the G-protein will then activate adenylate cyclase, which in turn will activate ATP and transform it into cAMP. It is cyclic AMP (cAMP) which will finally relay the original message sent through the hormone, to the genetic material of the cell.
