Question

Name the enzyme that converts starch into maltose.

• A. Amylase
• B. Maltase
• C. Lipase
• D. Protease

Answer 1

The correct option is A

Amylase

The correct option is A:

Explanation for Correct option:

1. The enzyme that converts starch into maltose is amylase.
2. Maltose is a disaccharide made up of two glucose units, whereas starch is polysaccharide made up of amylose and amylopectin.
3. Amylase degrades glycosidic bonds.

Explanation for Incorrect options:

Option B:

1. Maltase causes the hydrolysis of the disaccharide maltose to two monomeric units of glucose.
2. The enzyme is found in plants, microorganisms, humans and different vertebrates.

Option C:

1. Lipase is an enzyme the body uses to breakdown the fat molecules in food, so that they can be absorbed from the digestive organs.
2. Lipase is synthesised in the pancreas and the mouth.
3. The vast majority of people produce sufficient pancreatic lipase. However, individuals with cystic fibrosis, Crohn illness, and celiac sickness might not have sufficient lipase to get the sustenance they need from food.

Option D:

1. Proteases (proteolytic enzymes) are catalysts that hydrolyse proteins.
2. Proteins in the body or on the skin are broken down by proteolytic enzymes.
3. These enzymes hydrolyse the peptide bonds between the amino acids of proteins.

Final answer: Amylase converts starch into maltose.
