Question

An enzyme deficiency commonly seen in African Americans and Native Americans is

1: lactase.
2: maltase.
3: amylase.
4: sucrase.

Answer 1

Lactose intolerance is a common condition caused by a deficiency of the enzyme lactase, while G6PD deficiency is the most common enzyme deficiency in humans.

Step-by-step explanation:

Lactose intolerance is a condition in which the enzyme lactase is deficient or absent, leading to the inability to digest lactose found in milk. It is more common in the Asian population.

On the other hand, glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common enzyme deficiency in humans, especially in African-American males. This deficiency results in a shortage of the enzyme glucose-6-phosphate dehydrogenase, which is responsible for preventing the abnormal breakdown of red blood cells.
