Biology- Maintaining a Balance Summary 1. Most organisms are active in a limited temperature range 1. identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates Enzymes are proteins which act as catalysts in living things (they lower the amount of energy needed for a reaction‚ therefore increasing rate of reaction). Enzymes speed up reactions but are not used up by them. Enzymes catalyze only one

Endometriosis Introduction Endometriosis is a gynecological medical condition in which cells from the lining of the uterus (endometrium) appear and flourish outside the uterine cavity‚ most commonly on the membrane which lines the abdominal cavity. The uterine cavity is lined with endometrial cells‚ which are under the influence of female hormones. Endometrial-like cells in areas outside the uterus (endometriosis) are influenced by hormonal changes and respond in a way that is similar to the cells

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
