Question

the chemical digestion occurs mainly in the ____. a large intestine b mouth c liver d small intestine

Explanation:

Chemical digestion involves breaking down food into smaller molecules through enzymes and other chemicals. The small intestine receives digestive enzymes from the pancreas and bile from the liver, and is the main site for chemical digestion of proteins, carbohydrates, and fats. The large intestine mainly absorbs water and electrolytes. The mouth starts carbohydrate digestion with salivary amylase but is not the main site. The liver produces bile which aids digestion but is not where most chemical digestion occurs.

Answer:

d. Small intestine
