Q5. The phosphorylase enzyme, which is involved in breakdown of glycogen to glucose, is controlled by both allosteric mechanisms and posttranslational modification. A) Describe how the T to R transition and activity of glycogen phosphorylase would change under the following conditions: i) high AMP levels and activation of phosphoprotein phosphatase, ii) activation of phosphorylase kinase, ili) activation of phosphorylase kinase and high glucose levels. B) What properties would an uncompetitive inhibitor of glycogen phosphorylase have, what would the Lineweaver Burk...

An enzyme binds to a competitive inhibitor with Kd = 1.2 × 10-6 M at pH 7.0 and 25°C.
An enzyme binds to a competitive inhibitor with Kd = 1.2 × 10-6 M at pH 7.0 and 25°C.(a)At what inhibitor concentration will 75% of the enzyme be bound to the inhibitor if there is no substrate present? (b) This enzyme has a Km of 4.0 × 10-5 M and a Vmax of 50 μM/s. At a substrate concentration of 3.0 × 10-4 M, calculate (i) the velocity of reaction in the presence of the inhibitor at 4.8 x 10-5 M (ii) the degree of...
