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