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.

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 activates protein kinase A?
Protein kinase A is activated by the binding of cyclic AMP (cAMP) to its regulatory subunits, causing the catalytic subunits to be released and become active.
Is protein kinase an enzyme?
Yes, protein kinase is an enzyme.
Which protein can be phosphorylated by protein kinase AA?
The protein that can be phosphorylated by protein kinase AA is called protein X.
How does the activation of protein kinase A affect the regulation of glycolysis?
When protein kinase A is activated, it can increase the rate of glycolysis by phosphorylating enzymes involved in the glycolytic pathway. This phosphorylation can lead to the activation of these enzymes, resulting in an overall stimulation of glycolysis and increased production of energy in the form of ATP.
What is the last step in the sequence of events when cyclic AMP acts as a second messenger?
the last step is ofcourse glycogen breakdown.......before that inactive glycogen phosphorylase-b is activated and phosphorylated to glycogen phosphorylase-a by the help of activated phosphorylase kinase........ ......phosphorylase kinase was activated by activated protien kinase..and activated protien kinase was activated by cyclic amp...........

What activates protein kinase A?
Protein kinase A is activated by the binding of cyclic AMP (cAMP) to its regulatory subunits, causing the catalytic subunits to be released and become active.
What has the author Susan Randall written?
Susan Randall has written: 'Interactions among the mitogen-activated protein kinase cascades and the identification of a novel cdc2-related protein kinase'
What is the role of cAMP in the signal transduction pathway activated by epinephrine?
It binds to and activates protein kinase A, which then phosphorylates other enzymes.
Is protein kinase an enzyme?
Yes, protein kinase is an enzyme.

Is protein kinase a second messenger involved in cellular signaling pathways?
No, protein kinase is not a second messenger in cellular signaling pathways. It is an enzyme that plays a key role in transmitting signals within cells by adding phosphate groups to proteins. Second messengers are small molecules that relay signals from cell surface receptors to target molecules inside the cell.
Is there other names for Polo?
# Cell cycle regulated protein kinase # HGNC:9077 # PLK # PLK 1 # PLK prov # PLK1 # Polo like kinase 1 # Serine threonine protein kinase 13 # Serine/threonine protein kinase PLK 1 # Serine/threonine protein kinase PLK1 # STPK 13 # STPK13
How are kinases activated in cellular signaling pathways?
Kinases are activated in cellular signaling pathways through a process called phosphorylation. This involves the addition of a phosphate group to the kinase protein, which changes its shape and activates its function. This activation allows the kinase to transfer phosphate groups to other proteins, triggering a cascade of signaling events within the cell.
Is kinase a protein?
Yes, a kinase is a type of protein that helps regulate cellular processes by adding phosphate groups to other proteins.
