Summary

Proteins, fats, and carbohydrates are made up of smaller, chemically simpler subunits. Macromolecules are assembled by dehydration synthesis and are disassembled by hydrolysis. These reactions either add or remove a molecule of water. Each macromolecule has a corresponding enzyme that speeds up chemical reactions such as hydrolysis. Enzymes are designed to have an active site for a specific molecule, or substrate, on its surface.

Factors, such as fluctuations in temperature or pH, can affect the shape of an enzyme and, therefore, its ability to bind with a substrate molecule.

The organs of the digestive system work together to break these macromolecules down into subunits for absorption. Nutrient absorption, occurring primarily in the small intestine, provides cells with the necessary resources to maintain and repair cellular function.

Traditional medicine incorporates the use of herbal and spiritual remedies to cure illness. In contrast, Western medicine often approaches the treatment of disease by drugs, invasive medical treatments, and surgery. By investigating a variety of diseases, you discovered how disorders interrupt the body's natural exchange of matter and flow of energy. Both traditional and Western medicines attempt to restore homeostatic balance to your body system. However, medicine cannot cure all diseases. Being healthy is a function of smart lifestyle choices and available technology that can help you maintain or restore homeostasis.
