During gluconeogenesis, which enzyme must be present in addition to the glycolytic enzymes?

Question

Quizplus · Accepted Answer

Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate substrates such as amino acids, lactate, and pyruvate. The enzymes used in gluconeogenesis are essentially the reverse of the enzymes used in glycolysis, but there are a few exceptions. One of these exceptions is the enzyme fructose 1,6-bisphosphate phosphatase, which is required for the conversion of fructose 1,6-bisphosphate to fructose 6-phosphate. This step is necessary in order to bypass the irreversible step catalyzed by phosphofructokinase in glycolysis. Therefore, the correct answer is A) fructose 1,6-bisphosphate phosphatase.
