Question

A child took sugarcane and sucked its juice. Regarding this, which of the following matches is correct?
Substrate Enzyme Site of secretion of enzyme Products formed
A. Protein’s- Pepsin, Duodenum, Polypeptides
B. Starch- Amylase, Salivary glands, Glucose
C. Lipids- Lipase, Pancreas, Fat globules
D. Sucrose- Invertase, Duodenum, Glucose+fructose

Answer 1

Hint: Enzyme is responsible for the sweet taste of sucrose. The major digestion takes place in the small intestine and the digestion breaks the compounds into simpler complexes.

Step by step answer:A substrate is a molecule that binds with an enzyme to act on it. These are generally proteins or carbohydrates. An enzyme is a protein molecule that speeds up a reaction by decreasing the activation energy. Activation energy is the energy required in a reaction to initiate it.
The site of secretion of an enzyme is the location where the enzyme is produced. Products formed are products formed after the reaction. The juice of sugarcane has a sweet taste because of the presence of sucrose. Sucrose is a disaccharide. It is a common sugar. It is composed of two monosaccharides which are glucose and fructose. It is produced by plants, naturally. When the juice is ingested, the digestion begins. The juice travels down the esophagus and the stomach and reaches the upper small intestine or duodenum. The duodenum then secreted an enzyme called invertase in order to digest the sucrose. Invertase binds on sucrose and breaks it into simpler compounds. Those compounds are glucose and fructose as these are the compounds sucrose is made of.
So, the correct option is option D.

Note: Invertase is one of the secret ingredients used in the candy-making industry. It is an enzyme that is commonly utilized to make candy liquid centers, fondant candies, creme eggs, chocolate-covered cherries and other cordials. Invertase is usually obtained from yeast. Major yeast producing locations are bread factories or beer breweries.
