Why would measuring blood glucose levels in an individual 15 to 60 minutes after they drink a liter of milk indicate whether they are able to digest lactose?Group of answer choicesWhen lactose enters the large intestine, glucose is digested by bacteria and then enters the bloodstream.When lactose is digested by lactase, the glucose that is produced enters the bloodstream from the small intestine.The fats and proteins in milk are digested by the body, causing glucose levels in the blood to increase.When lactose is digested by lactase in the small intestine, different cells in the body start releasing glucose into the bloodstream.

Why would measuring blood glucose levels in an individual 15 to 60 minutes after they drink a liter of milk indicate whether they are able to digest lactose?Group of answer choicesWhen lactose enters the large intestine, glucose is digested by bacteria and then enters the bloodstream.When lactose is digested by lactase, the glucose that is produced enters the bloodstream from the small intestine.The fats and proteins in milk are digested by the body, causing glucose levels in the blood to increase.When lactose is digested by lactase in the small intestine, different cells in the body start releasing glucose into the bloodstream.
Solution
The correct answer is: "When lactose is digested by lactase, the glucose that is produced enters the bloodstream from the small intestine."
Here's why:
Lactose is a sugar found in milk and other dairy products. In order for our bodies to use lactose, it must first be broken down by an enzyme called lactase, which is found in the small intestine. This process breaks lactose down into two simpler sugars: glucose and galactose.
When a person drinks milk (or consumes any other lactose-containing food), their lactase levels should rise to digest the lactose. If they are able to digest lactose properly, the glucose and galactose are then absorbed into the bloodstream through the walls of the small intestine. This causes a rise in blood glucose levels, which can be measured.
If a person is lactose intolerant, they do not produce enough lactase to break down the lactose. As a result, the lactose is not broken down and absorbed in the small intestine, and instead travels to the large intestine, where it can cause symptoms like bloating, diarrhea, and gas. In this case, there would not be a significant rise in blood glucose levels after consuming lactose, because the lactose is not being broken down and absorbed as glucose.
Therefore, by measuring blood glucose levels 15 to 60 minutes after a person drinks a liter of milk, you can get an indication of whether or not they are able to digest lactose. If their blood glucose levels rise, it suggests they are digesting the lactose properly. If their blood glucose levels do not rise, it suggests they may be lactose intolerant.
