Olivine is the naming of group-producing minerals, which are usually found in ultramafic and mafic rocks, like gabbro, basalt, diabase, dunite, and peridotite. They are generally green in appearance and exhibit constituents, which generally range between Fe2SiO4 and Mg2SiO4.

Which of the following describes the role of cyclic amp (cAMP) <br><br> in hormone responses
Anon25 [30]

Hello. You forgot to enter the answer options. The options are:

"A. cAMP opens a pore for steroid hormones to enter the nucleus. B. cAMP receives a message from a nonsteroid hormone and carries the message into the cell. C. cAMP receives messages from mRNA to begin protein synthesis. D. cAMP are molecules that bind and captures the nonsteroid hormone"

Answer:

cAMP receives a message from a nonsteroid hormone and carries the message into the cell.

Explanation:

cAMP is a very important molecule for the functioning of our organism. That's because cAMP is a cellular messenger responsible for receiving a message from a non-steroid hormone and carrying it to the cell.

The cAMP is formed by the enzyme adenylyl cyclase, which is present on the inner side of the membranes. This enzyme catalyzes a reaction with the ATP molecule, giving rise to cAMP.
