Question

Acute intermittent porphyria is a defect in what?

A) Glycolysis
B) Heme synthesis
C) Citric acid cycle
D) Pentose phosphate pathway

Answer 1

Acute intermittent porphyria is a metabolic disorder that results from a defect in heme synthesis, particularly due to a deficiency in the enzyme porphobilinogen deaminase.The correct answer is option B.

Step-by-step explanation:

Acute intermittent porphyria is a defect in B) Heme synthesis. This genetic disorder is characterized by a deficiency in one of the enzymes required for the synthesis of heme, an essential component of hemoglobin and certain other proteins. Specifically, the most common form of acute intermittent porphyria results from a deficiency of the enzyme porphobilinogen deaminase, which is a key enzyme in the heme synthetic pathway.The correct answer is option B.
