The correct answer is:<\/p>\n\n\n\n

D. Sodium bicarbonate neutralizes the acidity of chyme.<\/strong><\/p>\n\n\n\n

Explanation:<\/strong><\/p>\n\n\n\n

Sodium bicarbonate is an important secretion from the pancreas with a crucial role in the digestive process. Its primary function is to neutralize the acidity of chyme as it exits the stomach and enters the small intestine. Here\u2019s a more detailed look at why this function is vital:<\/p>\n\n\n\n

    \n
  1. Chyme’s Acidity:<\/strong> Chyme is a semi-liquid substance resulting from the digestion of food in the stomach. It is highly acidic due to the presence of gastric acid (primarily hydrochloric acid) secreted by the stomach lining. This acidic environment helps to denature proteins and activate pepsin, an enzyme involved in protein digestion. However, once the chyme moves from the stomach to the small intestine, its high acidity can be detrimental.<\/li>\n\n\n\n
  2. Neutralization by Sodium Bicarbonate:<\/strong> The small intestine, especially the duodenum, requires a more neutral to slightly alkaline environment for optimal enzyme activity. Enzymes such as pancreatic amylase, lipase, and proteases (e.g., trypsin and chymotrypsin) are essential for the digestion of carbohydrates, fats, and proteins, respectively. These enzymes function best at a neutral or slightly alkaline pH. Sodium bicarbonate, released by the pancreas into the small intestine, neutralizes the acidic chyme, creating a more suitable environment for these digestive enzymes to work efficiently.<\/li>\n\n\n\n
  3. Protective Function:<\/strong> By neutralizing stomach acid, sodium bicarbonate also helps to protect the lining of the small intestine from being damaged by the acidic chyme. The intestine\u2019s mucosa is adapted to handle a neutral or slightly alkaline environment and could be damaged by continuous exposure to acid.<\/li>\n\n\n\n
  4. Digestive Enzyme Activation:<\/strong> In addition to providing an optimal pH for enzyme activity, the neutralization of stomach acid ensures that digestive enzymes secreted by the pancreas and the small intestine are in their active forms. This is crucial for the complete digestion and absorption of nutrients.<\/li>\n<\/ol>\n\n\n\n

    In summary, sodium bicarbonate\u2019s role in neutralizing the acidity of chyme is essential for maintaining a conducive environment for enzyme action and protecting the intestinal lining. This process is crucial for effective digestion and nutrient absorption.<\/p>\n","protected":false},"excerpt":{"rendered":"
