Question

The mitochondrial form of the PEPCK enzyme, with oxaloacetate as substrate, is a(n)__________enzyme for the Citric Acid Cycle

(a) inhibitory
(b) activatory
(c) anapleurotic
(d) catapleurotic

Answer 1

(d) catapleurotic

Step-by-step explanation:

Phosphoenolpyruvate carbokinase (PEPCK) is usually used in the conversion of oxaloacetate to phosphoenolpyruvate (an important intermediate in glycolysis and gluconeogenesis, C₃H₅O₆P). The main function of this catapleurotic enzymes is in the catalysis of the forward conversion of oxaloacetate to phosphoenolpyruvate.
