Digestive Enzymes: Breaking Down Food for Nutrient Absorption

The video explains how digestion converts large molecules into smaller ones for nutrient absorption. It covers chemical and mechanical digestion, focusing on enzymes as biological catalysts. Carbohydrates, proteins, and lipids are broken down by specific enzymes: carbohydrases, proteases, and lipases. The lock-key model illustrates enzyme specificity. Factors like temperature and pH affect enzyme activity. Metabolism, the sum of all chemical reactions in the body, relies on enzymes to proceed at life-sustaining rates.
