Which of the following is NOT a characteristic of acetyl-CoA carboxylase?
A)competitive inhibition by palmitoyl-CoA
B)biotin carboxylase and transcarboxylase subunits
C)biotin carboxyl carrier protein subunits
D)citrate shifting the enzyme toward the active polymer

Question

Quizplus · Accepted Answer

Acetyl-CoA carboxylase is not competitively inhibited by palmitoyl-CoA; instead, palmitoyl-CoA allosterically inhibits the enzyme. This enzyme is characterized by having biotin carboxylase and transcarboxylase subunits, biotin carboxyl carrier protein subunits, and being activated by citrate, which shifts the enzyme toward its active polymer form.
