3.

If the regulatory subunit of PKA is not bound by cAMP, then the catalytic subunit is free to phosphorylate intracellular proteins.

A)

True

B)

False

Explanation / Answer

3.its true

in cell biology protien kinase a is an enzyme whose activity depends up on the cellular levels of the cyclic AMP.

pka is also known as c-AMP PROTIEN DEPENDENT KINASE ,becuase it has traditionally been through activated through release of catalytic subunits and phosphorylate.

4.epinephrine are also called as adrenaline .it is a neurotransmittor ,it plays an important role in thje fight and flight response by increasing the blood flow to muscles.

epinephrine binds both alpha and beta receptors but in the liver binds the beta adrenergic receptors and glucose is converted to glycogen.
