Chemical digestion in the stomach primarily occurs through the action of gastric juices, which contain hydrochloric acid (HCl) and digestive enzymes like pepsin. The acidic environment helps denature proteins, making them more accessible for enzymatic breakdown. Pepsin, activated from its precursor pepsinogen by the acidic pH, specifically targets and digests proteins into smaller peptides. This process transforms food into a semi-liquid mixture called chyme, ready for further digestion in the small intestine.
no in the mouth
most chemical digestion occur starting from duoduenum, small intestine. starch start from saliva in mouth, protein in stomach.
Most nutrient digestion occurs in the stomach
No, digestion begins in the mouth but also occurs in the stomach and small intestine.
what is responsible for chemical digestion in earthworms
Most chemical digestion occurs in the stomach and absorption occur in the intestines in humans and many other animals.
two organs where digestion occur are stomach and small intestine
does absorption occur when mechanical or chemical digestion
in the mouth (saliva) in the stomach (stomach acid)
carbohydrate digestion doesn't occur in the stomach and the large intestine.
Antacids affect chemical digestion by increasing the pH in the stomach.
