Which of the following statements in not correct about lactose intolerance?
  1. It is due to the deficiency of enzyme which converts galactose into glucose
  2. Deficiency of lactase enzyme is associated with inttolerance of milk
  3. It leads to flatulence
  4. Curd is better tolerated than milk in intolerant individuals

A
Deficiency of lactase enzyme is associated with inttolerance of milk
B
Curd is better tolerated than milk in intolerant individuals
C
It is due to the deficiency of enzyme which converts galactose into glucose
D
It leads to flatulence
Solution
Verified by Toppr

A deficiency of lactase - an enzyme produced in your small intestine - is usually responsible for lactose deficiency leads to symptoms after we eat dairy foods.
So, the correct option is 'Deficiency of lactase enzyme is associated with intolerance of milk.'

Study the given data and answer the questions that follow. A sample of an enzyme called lactase was isolated from the intestinal lining of a calf. Assays were undertaken to evaluate the activity of the enzyme sample. The substrate of lactase is the disaccharide lactose. Lactase breaks a lactose molecule in two, producing a glucose molecule and a galactose molecule. Two assays were carried out.

Q5
Statement 1: Lactose intolerant people cannot consume any form of milk products.

Statement 2: Milk contains lactose, a sugar that cannot be digested by lactose intolerant people but can it can be consumed if it is metabolised into its sub-constituents as in curds/cheese and other dairy products.
