Q. Which one of the following is the correct matching of the site of action on the given substrate enzyme action upon it and the end-product?
A) $Duodenum - \ Triglycerides\underset{Monoglycerides}{\overset{\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ Trypsin\ \ \ \ \ \ \ \ \ \ \ \ }{\rightarrow}}$
B) $Small\ intestine - Starch\underset{\ Disaccharide(maltose)}{\overset{\ \ \ \ \ \ \ \ \ \ \ \ \alpha - Amylase\ \ \ \ \ \ \ \ \ \ \ \ \ }{\rightarrow}}$
C) $Small\ intestine - \ Proteins\ \overset{\ \ \ \ \ Pepsin\ \ \ \ \ }{\rightarrow}\$ $\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ Amino\ acids$
D) $Stomach - \ Fats\overset{\ \ \ \ \ Lipase\ \ \ \ \ }{\rightarrow}Micelles$
Explanation
The pancreatic juice contains $\alpha$-amylase, Which converts starch into maltose, isomaltose and $\alpha$-dextrins in small intestine. $Starch\ \overset{\ \ \ \ \ \alpha - amylase\ \ \ \ \ }{\rightarrow}\ Maltose\ (disaccharide)$
