A second messenger system is a signaling pathway employed by cells to transmit signals from the cell membrane to the cytoplasm or nucleus. It involves the activation of specific molecules (second messengers) in response to an initial extracellular signal, which then propagate the signal within the cell to elicit a cellular response. Common second messengers include cAMP, Ca2+, and IP3.

Which of the following does not act as a second messenger in the second messenger system calmodulin or inositol triphosphate or cyclic AMP?

inositol triphosphateInositol triphosphate (IP3) and diacylglycerol (DAG) are important second messengers. Their formation begins with the binding of an extracellular regulatory


Which one of these hormones does not act on a second messenger system is it Glycogen Epinephrine growth hormone or testosterone or acth which one?

Testosterone does not act on a second messenger system. Testosterone acts directly on genes within a cell to initiate cellular changes, whereas the other hormones listed (Glycogen, Epinephrine, Growth Hormone, ACTH) typically use second messenger systems to transmit their signals inside the cell.


Does direct gene activation involve a second-messenger system?

No, direct gene activation typically does not involve a second-messenger system. Direct gene activation involves specific transcription factors binding directly to gene promoter regions to regulate gene expression. Second-messenger systems are typically involved in signal transduction pathways that lead to changes in protein activity or cell function, rather than directly activating genes.
