Answer:
Liver phosphorylase a concentration decreases when glucose enters the blood.
The binding of glucose to liver phosphorylase a shifts the equilibrium from the active form
As the concentration of phosphorylase a decreases, the activity of glycogen synthase increases. to the inactive form
Explanation:
Protein phosphatase 1 (PP1) is a phosphatase enzyme known to remove phosphate groups from serine/threonine amino acid residues. PP1 plays diverse biological roles including, among others, cell progression, control of glucose metabolism, muscle contraction, etc. In glucose metabolism, PP1 regulates diverse glycogen metabolizing enzymes (e.g., glycogen synthase, glycogen phosphorylase, etc). In the liver, glycogen phosphorylase catalyzes the rate-limiting step in glycogenolysis by releasing glucose-1-phosphate. Glycogen phosphorylase <em>a</em> is converted (and inactivated) into the <em>b</em> form by PP1, which catalyzes the hydrolysis of the phosphate bond between serine and the phosphoryl group. In the liver, glucose binds in order to inhibit glycogen phosphorylase <em>a</em>, thereby inducing the dissociation and activation of PP1 from glycogen phosphorylase <em>a</em>.

Nitric oxide accomplishes this by elevating cGMP levels.
- NO is a distinctive message. It is a gas, although it does dissolve in an aqueous solution.
- It is a free radical with an unshared electron, which will react with thiol groups on proteins to form new complexes.
- Unlike other second messengers, NO doesn't need energy to move inside and outside of cells. It can go where it wants, but it does not travel far because it is a reactive free radical.
- NO acts within the cell that produces it as a second messenger. It operates as a paracrine molecule able to travel 10–20 cell diameters to affect the biology in surrounding cells. It can form complexes with proteins like hemoglobin, glutathione, and other proteins and then separate from those complexes.
Therefore, increasing cGMP levels is necessary.

As a theory of value, hedonism states that all and only pleasure is intrinsically valuable and all and only pain is intrinsically not valuable. Hedonists usually define pleasure and pain broadly, such that both physical and mental phenomena are included.
