HUMAN NUTRITION

Detailed explanation-1: -Digestion is a form of catabolism or breaking down of substances that involves two separate processes: mechanical digestion and chemical digestion. Mechanical digestion involves physically breaking down food substances into smaller particles to more efficiently undergo chemical digestion.

Detailed explanation-2: -Chemical and mechanical digestion are the two methods your body uses to break down foods. Mechanical digestion involves physical movement to make foods smaller. Chemical digestion uses enzymes to break down food.

Detailed explanation-3: -Digestion systems are classified into four types: monogastric, avian, ruminant, and pseudo-ruminant.

Detailed explanation-4: -Physical digestion helps to break down large food particles into smaller particles, whereas chemical digestion breaks large particles into small molecules. Chemical digestion involves enzymes and enzymatic actions, whereas physical digestion involves physical actions including chewing, mashing and breaking food.

Detailed explanation-5: -Amylase, maltase, sucrase, lactase, etc. Fats are converted to fatty acids and glycerol by lipases in the small intestine. Trypsin, chymotrypsin, pepsin, dipeptidases, etc. More items
