The enzyme lactase helps the digestive system break down lactose, a disaccharide found in milk, into the monosaccharides glucose and galactose. Lactose-intolerant individuals have low levels of lactase production and therefore have difficulty digesting dairy products. A common test for lactose intolerance is to measure blood sugar (glucose) levels after consuming a drink containing lactose. Which of the following test results would you expect to see for a lactose-intolerant person? Multiple Choice Blood sugar levels are unaffected by drinking a lactose solution Blood sugar levels is rapidly immediately after anning actose solution Blood or even roetely one in conto

Respuesta :

The expected test result for a lactose-intolerant person is Blood sugar levels are unaffected by drinking a lactose solution.

Lactose is divided into glucose and galactose during digestion by the enzyme lactase, which is produced by the cells of the small intestine. Lactase enzyme is not formed in lactose intolerant people. As a result, when a lactose-intolerant person consumes lactose solution, lactose is not completely digested and is not broken down into the two monosaccharides glucose and galactose. The villi of the small intestine do not absorb glucose, so drinking a lactose solution by a lactose-intolerant person has no effect on blood sugar levels.

Because lactose is not entirely digested in lactose-intolerant people, blood sugar levels do not rise rapidly after drinking lactose solution. Lactose consumption by lactose-intolerant people has no effect on blood sugar levels because there is no complete digestion. As a result, drinking a lactose solution does not cause a rapid drop in blood sugar levels.

As a result, the correct answer is that drinking lactose solution has no effect on blood sugar levels.
