What is the second largest group of vertebrates?
Mammals
What does a second messenger always do?
read it:)
Cellular responses to hormones that initiate second-messenger systems include?
Possible activation of several different second messenger systems.
What was the second NASA mission to Mercury called?
"Messenger".
What is cyclic AMP produced by?
Cyclic AMP (cAMP) is produced by the enzyme adenylate cyclase, which converts ATP into cAMP in response to various signaling molecules such as hormones or neurotransmitters. The cAMP molecule then acts as a second messenger to relay extracellular signals into the cell to regulate various cellular processes.
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
What is the difference between first messenger and second messenger?
The first messenger is nothing but referred to the molecule that brings information upto the cell surface. Once this molecule transfers signal to cell, it is taken over by the well known second messenger to take it further to nucleus through various other signaling molecules down the cascade.
What news does the Second Messenger announce?
The suicide of Jocasta, Oedipus' wife.
What is the mechanism by which protein kinase A is activated by the second messenger?
Protein kinase A is activated by the second messenger through a process called phosphorylation. When the second messenger binds to the regulatory subunit of protein kinase A, it causes a conformational change that releases the catalytic subunit. This released catalytic subunit is then able to phosphorylate target proteins, leading to various cellular responses.
Is GTP considered a second messenger?
GTP (guanosine triphosphate) is not typically classified as a second messenger; instead, it is a nucleotide that serves primarily as an energy source in cellular processes and as a substrate for RNA synthesis. However, GTP can play a role in signal transduction, particularly through G-proteins, which are activated by GTP binding. When a G-protein is activated, it can then influence other signaling pathways, effectively functioning in a manner similar to second messengers. Thus, while GTP itself is not a second messenger, it is integral to the activity of proteins that mediate second messenger pathways.
What is the largest order of mammals?
The largest order of mammals, with about 1,700 species, is rodents. Bats are second with about 950 species.
A neurotransmitter whose function depends on a second messenger is known as?
A neurotransmitter whose function depends on a second messenger is known as a neuromodulator. Neuromodulators can influence the behavior of neurons by affecting processes like signal transduction or synaptic transmission.
