Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following statements about food as it enters the duodenum is incorrect?
A
Sugars are changed into glucose
B
Starch Is changed into maltose
C
Fats are absorbed
D
Proteins are changed into peptones
Explanation: 

Detailed explanation-1: -As pancreatic lipase enters the small intestine, it breaks down the fats into free fatty acids and monoglycerides.

Detailed explanation-2: -When food moves into your duodenum, it mixes with digestive enzymes that your pancreas secretes. These enzymes break down the largest molecules of food, such as proteins and starches. They also neutralize stomach acid.

Detailed explanation-3: -After foods mix with stomach acid, they move into the duodenum, where they mix with bile from the gallbladder and digestive juices from the pancreas. The absorption of vitamins, minerals, and other nutrients begins in the duodenum. Food passes from the stomach into the small intestine.

Detailed explanation-4: -Digestion of food is done by enzymes in the body. In human body, fats are digested in small intestine and in small intestine the fat is digested with the help of lipase enzyme. Hence statement first is wrong. Starch of food is digested by amylase not by the lipases so statement second is also wrong.
