Question

In the process of digestion, the enzymes 'X' in the salivary gland and 'Y' in the pancreas are such that 'X' converts starch into maltose and 'Y' converts proteins to amino acids. Identify X and Y.

• A. Trypsin and pepsin
• B. Ptyalin and trypsin
• C. Trypsin and lipase
• D. Lipase and ptyalin

Answer 1

The correct option is B Ptyalin and trypsin

During the process of digestion:

• Starch from the ingested food is transformed into maltose by the enzyme present in the salivary glands known as salivary amylase/ptyalin.
• Trypsin is an enzyme present in the pancreatic juice and is secreted by the pancreas. This enzyme helps in digestion of proteins and converts them into amino acids.
