"When adenylyl cyclase is activated, it catalyses the conversion of ATP to cyclic AMP, which leads to an increase in intracellular levels of cyclic AMP. Cyclic AMP functions as a "http://wiki.answers.com/../pathphys/endocrine/moaction/surface.html" to relay extracellular signals to intracellular effectors, particularly http://wiki.answers.com/pka.html.

What else can I help you with?
Which enzyme is activated by epinephrine?
adenil cyclase
What catalyzes the conversion of ATP to cAMP?
Adenylate cyclase is the enzyme that catalyzes the conversion of ATP to cAMP (cyclic adenosine monophosphate). It does this by removing two phosphate groups from ATP, resulting in the production of cAMP.
What enzyme is activated by cAMP?
Protein kinase A (PKA) is activated by cAMP (cyclic adenosine monophosphate). Once activated, PKA plays a crucial role in many cellular processes by phosphorylating target proteins.
What is the correct order of events for hormones activating Gs proteins?
Hormone binds to G protein-coupled receptor (GPCR). GPCR undergoes a conformational change and activates the Gs protein. Gs protein activates adenylyl cyclase, leading to the production of cyclic AMP (cAMP). cAMP activates protein kinase A (PKA), initiating a cellular response.
How is pepsinogen activated in the stomach to become the active enzyme pepsin?
Pepsinogen is activated in the stomach by the acidic environment, which triggers a change in its structure to become the active enzyme pepsin.

Which is the correct order of events for hormones activating Gs proteins?
Activation of G protein, binding of GTP, activation of adenylate cyclase, conversion of ATP to cAMP
What is the 1st messenger of Cyclic AMP and cGMP?
The first messenger for cyclic adenosine monophosphate (cAMP) is a hormone or ligand that binds to a G protein-coupled receptor, leading to activation of adenylate cyclase and conversion of ATP to cAMP. For cyclic guanosine monophosphate (cGMP), the first messenger is typically nitric oxide (NO) which activates guanylyl cyclase leading to the production of cGMP from GTP.
How does forskolin burn fat and promote weight loss?
Forskolin activates an enzyme called adenylate cyclase, which increases levels of a molecule called cAMP in the body. This process can help to break down stored fat and increase metabolism, leading to potential weight loss.
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.
What is the correct order of events for hormones activating Gs proteins?
Hormone binds to G protein-coupled receptor (GPCR). GPCR undergoes a conformational change and activates the Gs protein. Gs protein activates adenylyl cyclase, leading to the production of cyclic AMP (cAMP). cAMP activates protein kinase A (PKA), initiating a cellular response.
How opium affect neurotransmitter?
Opium or any opioid for that matter presynaptically inhibit transmission of excitatory pathways. Activation of any type of opioid receptor inhibits adenylate cyclase, resulting in a fall in intracellular cAMP and diminished action potential firing. This causes a reduced flow of nociceptive information to the brain
What is an adenylation?
An adenyl is the univalent radical derived from adenine.
What Cellular acetylcholine receptor is found in effector organs of the parasympathetic system?
The M2 muscarinic acetylcholine receptor is the primary receptor found in effector organs of the parasympathetic system. Activation of this receptor leads to inhibition of adenylate cyclase and decreased intracellular levels of cyclic AMP, resulting in various physiological responses in target tissues.
What is cyclic AMP concentration?
Cyclic AMP, or cAMP, is a small molecule that plays a critical role in cellular signaling. It is synthesized from ATP by the enzyme adenylate cyclase and acts as a second messenger to regulate various cellular processes, including metabolism, gene expression, and cell growth. The concentration of cAMP in a cell can vary depending on external signals and internal regulatory mechanisms.
