What happens to the lactase enzyme in someone suffering from lactose intolerance? A. The substrate lactose acts as an inhibitor to the lactase enzym
B. The body produces too much lactase enzyme
C. The lactase enzyme is shaped the wrong way and can't lock into place
D. The body produces too little lactase enzyme

choice D

Explanation:

The body produces too little lactase enzyme​.

Lactose intolerance occurs when your small intestine doesn't produce enough of lactase to digest milk sugar (lactose).

Lactose intolerance in adulthood is caused by gradually decreasing expression of the LCT gene after infancy, which occurs in most humans. LCT gene expression is controlled by a DNA sequence called a regulatory element, which is located within a nearby gene called MCM6.

Some individuals have inherited changes in this element that lead to sustained lactase production in the small intestine and the ability to digest lactose throughout life.

People without these changes have a reduced ability to digest lactose as they get older, resulting in the signs and symptoms of lactose intolerance.

answer: glucoamylase presented optimum activity at temperature of 55â°c, and, in the glycosidic bonds from the non-reducing ends of starch, resulting in the production of glucose. source and type of fermentation can affect the enzyme's properties

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.
