B- What are the clinical manifestations associated with the deficiency of these two enzymes? C- Write down the biochemical reaction and the name of the metabolic pathway that these two isoforms are involved in, and how many ATP is utilized by these two isoforms?Identify the type of regulation of enzyme activity seen in the following situations - for example, competitive inhibition, allosterism, phosphorylation, zymogen conversion, association-dissociation, feedback inhibition, etc. a. Trypinsogen, which is not catalytically active, is converted to the active enzyme trypsin by removal of a hexapeptide from the N-terminal end. b. The dimer protein kinases is catalytically inactive. Binding of cAMP causes protein kinase dimer to split into its monomer which are active catalysts.

- For each of the statements below about the dUTPase enzyme, mark whether it is true or false. If it is false, change the language to make the statement true. _______If the dUTPase enzyme is the rate determining step in a larger metabolic pathway, the reaction likely lies near to equilibrium and is irreversible. _______For the dUTPase reaction, it is not likely that DG’ = DG°’ _______ dUTPase has a higher affinity for its substrate than for its product, but both of these are higher than the affinity for the transition state _______Kinetic analysis of dUTPase using Michaelis-Menten methods assumes that the formation of the E*S complex has a large negative value for DGThe clinical symptoms of two forms of galactosemia—deficiency of galactokinase or of UDPglucose: galactose 1-phosphate uridylyltransferase—show radically different severity.
