Which of the following enzymes is defective in the rare hereditary galactosemia?

Question

Quizplus · Accepted Answer

Galactosemia is caused by a deficiency of the enzyme galactose-1-phosphate uridylyl transferase, which is responsible for converting galactose-1-phosphate into glucose-1-phosphate. Deficiency of this enzyme leads to the accumulation of galactose-1-phosphate in the body, which can cause damage to organs and tissues, particularly the liver and brain. Galactokinase, phosphoglucomutase, and UDP-glucose pyrophosphorylase are not involved in the metabolism of galactose-1-phosphate and are not affected by galactosemia.
