Enzymes, Digestion and Absorption
infoWhy this? Enzymes catalyse metabolic reactions at rates compatible with life, linking protein structure to cellular function. Investigating how conditions and inhibitors affect their activity develops experimental skills and supports understanding of applications in medicine and industry. Digestion breaks large food molecules into absorbable products, while absorption transfers nutrients across the intestinal lining into the body's transport systems. Together, these processes explain how diet supplies materials for growth, repair, and metabolism.
scheduleWhy now? This unit brings together biological molecules, enzyme action, and membrane transport in a coordinated physiological process. It also develops understanding of specialised exchange surfaces before we compare them with gas exchange systems.
