Question:

A patient with Ritzolierre’s Disease would likely benefit from which of the following:
I. Injections of RZN45
II. Injections of JB-76
III. Injections of ascorbic acid
(A) I only
(B) II only
(C) III only
(D) II and III

The active site of the enzyme Ritzolinine (RZN45) contains three positively charged lysine residues. When ascorbic acid is present, binding of JB-76, the substrate of RZN45, decreases. The reaction rate is affected by the presence of ascorbic acid as shown in the figure below. It is thought that a daily supplement of Vitamin C might aid those suffering from Ritzolierre's Disease, which is caused by elevated levels of RZN45. Reaction Rate X Ascorbic Acid Present ---- Normal Concentration of JB-76
