Concept explainers
(a)
Interpretation: The process which occurs during the covalent modification of an enzyme using phosphorylation reaction has to be stated.
Concept introduction: The process of covalently modifying the structure of enzyme by linking or removing a group from the amino acid within the structure of enzyme is called covalent modification. This process alters the activity of the enzyme.
(b)
Interpretation: The process which occurs during the covalent modification of an enzyme using a phosphatase enzyme has to be stated.
Concept introduction: The process of covalently modifying the structure of enzyme by linking or removing a group from the amino acid within the structure of enzyme is called covalent modification. This process alters the activity of the enzyme.
