Question

Starting from the mouth, which enzymes are likely to act on the baked potato eaten by a man, as it moves down the alimentary canal?
A. Disaccharidase like maltase, lipases, nucleases
B. Salivary amylase, pancreatic amylase, disaccharidases
C. Salivary maltase, carboxypeptidase, trypsinogen
D. Pancreatic amylase, salivary amylase, lipases

Answer 1

Hint: Enzymes are proteins that accelerate metabolism or the chemical reactions in our bodies. They build some materials and break others down. All living things contain enzymes. Our bodies naturally generate enzymes. But enzymes are also in industrial products and food.

Complete step-by-step anwer:
An enzyme is a substance that serves as a catalyst in living organisms, which regulates the rate at which chemical reactions continue without itself being altered in the process. The biological processes that take place within all living organisms are chemical reactions, and most are controlled by enzymes. Baked potatoes contain starch which is a polysaccharide. In the oral cavity, the food is blended with saliva. The saliva contains an enzyme referred to as salivary amylase (also referred to as ptyalin) which turns starch into isomaltose, maltose, and tiny dextrins. Salivary amylase is stimulated in the saliva by the chloride ions. The pancreatic juice (present in the small intestine) comprises a starch digesting enzyme, known as a pancreatic amylase, which turns starch into isomaltose, maltose, and α-dextrins. Additionally, disaccharidases (present in the intestinal juice of the small intestine) degrade disaccharides into the simplest sugar.

Therefore the correct answer is Option B.

Note: Enzymes perform a large portion in the everyday running of the human body. Each cell in the human body comprises 1000 of enzymes. Enzymes function by combining with molecules to begin a chemical reaction. They function best at specific temperatures and pH levels. They perform a vital part in the proper working of the nervous system, the digestive system, muscles, and more.
