LITERATURE REVIEW INTRODUCTION OF ENZYMES Enzymes are complex proteins that cause a specific chemical change in all parts of the body (David C. Dugdale‚ 2011). When we understand enzymes we understand cells (Marshall Brian‚ 2001). In many organisms most chemical reactions are catalyzed -when a substance speeds up the rate of a chemical reaction- by enzymes. Each enzyme controls a certain function that happens in a cell. Still each one has its own process and rate that it converts molecules. Studying

Organisms that aren’t food producers must be food consumers. This method of nutrition is described as heterotrophic (eating others). Consumers include: predators‚ parasites‚ scavengers‚ decomposers and some green plants (e.g. sundews‚ Venus flytrap‚ pitcher plants). The food sources may be all or any of: plants‚ animals‚ fungi or bacteria; either living or dead. The advantages of the heterotrophic method of nutrition are: the food usually contains all the appropriate chemicals needed by

TOPIC 6‚ 11‚ & OPTION H: HUMAN HEALTH AND PHYSIOLOGY Digestive System Includes all the structures that are concerned with bringing food into the body to provide for the needs of the body’s cells. Each cell in an organism relies on a continuous expenditure of energy. Fats‚ carbs‚ and proteins are broken down during cellular metabolism and the energy derived from them is used to make ATP. The digestive system deals with: Ingestion‚ which is the bringing of nutrients into the body. Mechanical
