The correct answer is: \(\begin{array}{|c|c|c|c|} \hline \text{Substrate} & \text{Enzyme} & \text{Site of secretion of enzyme} & \text{Products formed} \\ \hline \text{Sucrose} & \text{Invertase} & \text{Duodenum} & \text{Glucose + Fructose} \\ \hline \end{array}\)
Sucrose (cane sugar; beet sugar; saccharose) is a sugar comprising one molecule of glucose linked to a fructose molecule. It occurs widely in plants and is particularly abundant in sugar cane and sugar beet \((15-20 \%)\), from which it is extracted and refined for table sugar. If heated to \(200^{\circ} \mathrm{C}\), sucrose becomes caramel. Sucrose is broken down into the monosaccharides glucose and fructose with the help of carbohydrate digesting enzyme, invertase, produced in the small intestine (duodenum).
