What is the site of most chemical digestion?

Question

Quizplus · Accepted Answer

The duodenum is the site of most chemical digestion, as this is where digestive enzymes from the pancreas and gallbladder mix with chyme (partially digested food from the stomach) to break down nutrients such as carbohydrates, proteins, and fats. The stomach does begin the digestion of proteins, but the majority of chemical digestion occurs in the small intestine, particularly the duodenum. The mouth is where mechanical digestion (chewing) and some chemical digestion (salivary amylase breaking down carbohydrates) occurs, but it is not the primary site of most chemical digestion. The cecum is primarily involved in absorbing water and electrolytes from indigestible food residue, and does not play a significant role in chemical digestion.
