Enzyme a Is Involved in the Metabolism of Metabolite C $\to$

Enzyme A is involved in the metabolism of metabolite C to metabolite D.Enzyme A is part of a linear pathway involving ten enzymes ultimately converting B $\to$ F.High levels of F directly alter the activity of enzyme A and result in control over the overall pathway.Enzyme A

A) likely has high rates of degradation and synthesis.
B) is likely a nonessential enzyme.
C) likely has low rates of degradation and synthesis.
D) is likely involved in a nonessential pathway.
E) none of the above
