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.

DIA [1.3K]

Answer:

The missing options are:

a. "It's due to insufficient production of vitamin B12 in the colon."

b. "Increased production of intrinsic factor in the stomach leads to this type of anemia."

c. "Overproduction of vitamin B12 in the large intestine can result in pernicious anemia."

d. "Decreased production of intrinsic factor by the stomach affects the absorption of vitamin B12 in the small intestine."

The correct answer is d. "Decreased production of intrinsic factor by the stomach affects the absorption of vitamin B12 in the small intestine."

Explanation:

Intrinsic factor is a protein that is produced by cells in the stomach, this protein is essential for the absorption of vitamin B12 in the small intestine. Without intrinsic factor, the absorption of vitamin B12 would be really low, causing pernicious anemia since vitamin B12 is necessary for the production of healthy red blood cells. If there is not a good production of healthy red blood cells that can distribute O₂ and CO₂, the body suffers from pernicious anemia.
