The answer is C. Atomic Number
The right option is Capsid
A capsid is a protein coat that
encloses the nucleic acid (RNA, DNA etc.) of a virus particle. Capsids are in different
shapes and the common ones are icosahedral, prolate, and helical. The main role
of the capsid is to protect the virus by ensuring that the nucleic acid inside
of it is safe.
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.
