Vedclass · Answer

(C) Statement $(1)$ is correct: Saliva contains electrolytes like $Na^+, K^+, Cl^-, HCO_3^-$ and salivary amylase.Statement $(2)$ is incorrect: Salivary amylase acts on starch at an optimum $pH$ of $6.8$,not $8.6$.Statement $(3)$ is correct: The intrinsic factor secreted by the parietal cells of the stomach is essential for the absorption of vitamin $B_{12}$ in the ileum.Statement $(4)$ is incorrect: The breakdown of di- and monoglycerides into fatty acids and glycerol is catalyzed by lipases,but the reaction provided in the question is incomplete and lacks the enzyme context; however,in the context of standard multiple-choice questions,$(1)$ and $(3)$ are definitively correct,making $(C)$ the most appropriate choice.
