Which phase is not an example of intracellular communication?

The two cells communicate when a single molecule is received by a signal reception at a short distance or long distance to produce cellular response. Transmission of a chemical signal between the cells of two different organisms is not an example of intercelluar communication.

What normally happens in a nuclear response?

When cell signaling causes a response in the nucleus, what normally happens? Proteins become transcription factors, certain genes are chosen, these are then transcribed.

What is the function of cyclic AMP?

Cyclic AMP is involved in the regulation of glycogen, sugar, and lipid metabolism. Cyclic AMP may affect brain function in many ways. In some cases, increase in levels of cAMP may result in an increase in the production of a neurotransmitter, contributing to an agonist effect.

What are the characteristics of a second messenger?

They include a wide variety of chemical species and have diverse properties that allow them to signal within membranes (e.g., hydrophobic molecules such as lipids and lipid derivatives), within the cytosol (e.g., polar molecules such as nucleotides and ions), or between the two (e.g., gases and free radicals).

How does cAMP act as a second messenger?

Adenosine 3′,5′-cyclic monophosphate (cAMP) is a nucleotide that acts as a key second messenger in numerous signal transduction pathways. cAMP regulates various cellular functions, including cell growth and differentiation, gene transcription and protein expression.

Is calmodulin a second messenger?

Calmodulin is a ubiquitous regulatory protein of the second-messenger system. It exhibits Ca2+-dependent regulatory activities toward several enzymes and proteins. The protein is implicated in a variety of cellular processes that are established as Ca2+-modulated. All calmodulins exhibit similar physical properties.

Which of the following is not a second messenger?

Complete answer: Sodium does not act as a second messenger for any hormone. Considering the other given options: -c GMP is also known as cyclic guanosine monophosphate. It acts as a second messenger by the mechanism of activation of protein kinases present within the cell.

Is Potassium a secondary messenger?

By way of achieving some uniformity among all living things, a role of potassium as a second messenger in plants extends the notion beyond prokaryotes where this element is seen as a second messenger in bacteria controlling gene expression and enzyme activity.
