Q. Which one of the following enzymetic reaction is incorrect?
A) Nucleic acids $\overset{\ Nucleotidase\ }{\rightarrow}$ Nitrogen bases + Pentose sugar
B) $\begin{matrix}
Fat \\
(Emulsified)
\end{matrix}\underset{Pancreatic}{\overset{\ \ \ \ \ \ Lipase\ \ \ \ \ \ \ }{\rightarrow}}$ Fatty acids + Diglycerids
C) Starch $\underset{Pancreatic}{\overset{\ \ \ \ \ \alpha\ amylase\ \ \ }{\rightarrow}}$ Maltose + Isomaltose + $\alpha$-dextrias
D) Proteins $\overset{\ Pepsin\ \ }{\rightarrow}$ Peptones + Proteose
Explanation
Digestion of nucleic acids takes place in the small intestine. The enzyme present in pancreatic and intestinal juices acts on nucleic acids as follows RNA $\underset{Pancreatic\ juice}{\overset{\ \ \ \ \ \ \ \ \ \ \ \ \ RNase\ \ \ \ \ \ \ \ \ \ \ \ }{\rightarrow}}$ Ribonucleotides Ribonucleotides (Nucleotides) $\overset{\ Nucleotidases\ }{\rightarrow}$ Nucleosides + $IPO_{4}$ Nucleosides $\overset{\ Nucleosidases\ }{\rightarrow}$ Nitrogenous base + Pentose sugar
