    Answer:

    With the inhibition of cyclic AMP phosphodiesterase in that cell, Kinase A will not be inactivated, so phosphorylase kinase will remain active.

    Explanation:

    Phosphodiesterase is an enzyme that has the function of hydrolyzing cAMP by converting it to AMP. As a result, a protein called kinase is inactivated and lipids break down in fat metabolizing cells. CAMP is a cellular messenger.

    Cyclic AMP phosphodiesterase, in turn, is an enzyme that catalyzes the conversion of cyclic AMP into a different molecule. as a result, a molecule called kinase A is deactivated. However, if inhibition of cyclic phosphodiesterase AMP in a muscle cell stimulated by adrenaline, Kinase A will not be deactivated, so phosphorylase kinase will remain active.

    The option that best predicts the effect of inhibiting cyclic AMP phosphodiesterase in a muscle cell stimulated by epinephrine is that phosphorylase kinase will remain active because protein kinase A will no longer be deactivated.

    • It should be noted that phosphodiesterase is an enzyme that’s vital in breaking phosphodiester bond. Phosphodiesterase help in the regulation of intracellular levels of cyclic guanosine monophosphate.
    • From the complete question, Phosphodiesterase is vital in hydrolyzing Cyclic AMP as it’s being converted to AMP. This will eventually lead to the inactivation of kinase.

    In conclusion, protein kinase A will no longer be deactivated and therefore, phosphorylase kinase will remain active.
