Reversible phosphorylation is a control mechanism used throughout metabolism. What are the general names of the enzymes involved in reversible phosphorylation and waht general reactions do they catalyze?
Homework Answers
ANSWER:-
Kimase is the enzyme.
kinases catalyze the addition of a phosphate group to a target
phosphatases catalyze the removal of a phosphate group from a target
And
In metabolic pathways, enzymes catalyzing essentially irreversible reactions are potential sites of control. In glycolysis, the reactions catalyzed by hexokinase,

What about their names identifies amylase and B-galactosidase as enzymes? Since enzymes are neither used up nor generated in the reaction, they are not included as a substrate or product when writing a chemical reaction. They are usually written over the arrow to signify that they catalyze or enhance the rate of the reaction. Write out the equation for the hydrolysis of ONPG including the enzyme (by name and number). Write out the reaction for the hydrolysis of starch including...
