NEET BIOLOGY

Detailed explanation-1: -Chemical digestion begins in your mouth. As you chew, your salivary glands release saliva into your mouth. The saliva contains digestive enzymes that start off the process of chemical digestion.

Detailed explanation-2: -Saliva contains special enzymes that help digest the starches in your food. An enzyme called amylase breaks down starches (complex carbohydrates) into sugars, which your body can more easily absorb. Saliva also contains an enzyme called lingual lipase, which breaks down fats.

Detailed explanation-3: -Collectively, all the major salivary glands function to secrete saliva, which contains a host of electrolytes, such as bicarbonate, and enzymes, such as salivary amylase, which break down carbohydrates in the oral cavity.

Detailed explanation-4: -Protein digestion begins when you first start chewing. There are two enzymes in your saliva called amylase and lipase. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids.

Detailed explanation-5: -Saliva releases an enzyme called amylase, which begins the breakdown process of the sugars in the carbohydrates you’re eating.
