$A$ and $R$ both are correct.

Vedclass · Answer

(A) Assertion $(A)$ is correct: In the buccal cavity,the chemical process of digestion is initiated by the hydrolytic action of the carbohydrate-splitting enzyme,the salivary amylase. About $30\%$ of starch is hydrolyzed here by this enzyme into a disaccharide—maltose. The optimum $pH$ for this enzyme is $6.8$.Reason $(R)$ is correct: The saliva secreted into the oral cavity contains electrolytes $(Na^+, K^+, Cl^-, HCO_3^-)$ and enzymes,salivary amylase and lysozyme. Lysozyme acts as an antibacterial agent that prevents infections.Conclusion: Both statements are correct,and the reason provides the necessary components of saliva that facilitate the process described in the assertion.

$(IV)$ Lipases	$(d)$ Nucleosides

$A-$ About $30\%$ of starch is hydrolyzed by salivary amylase (optimum $pH\, 6.8$) in the buccal cavity.
$R-$ The saliva secreted into the oral cavity contains electrolytes $(Na^+, K^+, Cl^-, HCO_3^-)$ and enzymes,salivary amylase and lysozyme.
