GCSE Biology - Digestive System #18
Cognito・2 minutes read
Humans need to consume carbohydrates, proteins, and fats which are broken down during digestion by enzymes in the mouth, stomach, and small intestine. The process involves physical and chemical breakdown of food to make essential nutrients absorbable.
Insights
- Enzymes like salivary amylase, pepsin, and pancreatic enzymes play a vital role in breaking down carbohydrates, proteins, and fats during the digestion process to make nutrients absorbable.
- The small intestine serves as a crucial site for most digestion to occur, with pancreatic enzymes and bile from the gallbladder working together to emulsify fats, highlighting the intricate processes involved in extracting essential nutrients from food.
