Final answer:
Lactose is a sugar found in milk and requires the enzyme lactase to be digested and absorbed in the human gut. Lactose intolerance occurs when individuals do not produce enough lactase.
Step-by-step explanation:
Lactose is a sugar found in milk and is absorbed in the human gut. However, lactose requires the enzyme lactase to be digested and absorbed in the human gut, so the correct answer is option 4) All of the above. Lactose intolerance occurs when individuals do not produce enough lactase, resulting in the inability to properly digest lactose and leading to symptoms such as bloating and abdominal cramps.
The statement about lactose that is NOT correct is that it is absorbed in the human gut. Lactose requires the enzyme lactase for proper digestion and absorption, and without it, lactose is not absorbed but moves to the large intestine, causing discomfort for those with lactose intolerance.
To answer the question of which statement is NOT correct about lactose, the information provided allows us to understand the characteristics and role of lactose in the human digestive system. According to the provided information, here are the facts about lactose:
Lactose is found in milk.
Lactose requires the enzyme lactase to be digested and absorbed in the human gut.
Many adults and some children are lactose intolerant because they lack sufficient lactase.
Based on this, the statement that is NOT correct about lactose is that it is absorbed in the human gut. Without the enzyme lactase, lactose cannot be properly digested and so it is not directly absorbed by the gut. Instead, the undigested lactose moves to the large intestine where it can cause discomfort and other symptoms associated with lactose intolerance.
