All Are Regulatory Mechanisms of HMG-CoA Reductase EXCEPT

All are regulatory mechanisms of HMG-CoA reductase EXCEPT:

A) low [cholesterol] increases mRNA for HMG-CoA reductase.
B) high [cholesterol] increases half-life for HMG-CoA reductase.
C) high [cholesterol] results in lower mRNA for HMG-CoA reductase.
D) phosphorylation by cAMP cascade inactivates HMG-CoA reductase.
E) phosphatases activate HMG-CoA reductase.
