**Metabolism** **What are the classification and functions of carbonhydrates?** Carbohydrates are the preferred source of energy and are classified as simple & complex and their function is to convert glucose to ATP. **What are the classification and functions of lipids?** Lipids are the next preferred source of energy and are classified as saturated and unsaturated EFA and their function is to Fuel source during activity Manufacture EFA's, transport fat soluble vitamins and cell functioning. **What are the classification and functions of proteins?** Proteins are the least preferred source of energy and are classified as structural functional growth & repair and their function is to manufacture of other proteins and act as hormones & enzymes & antibodies. **What are the classification and functions of fibre?** Fibre needs 25-30 gm/day (both insoluble & soluble) and are not classified and their function is to move foods along the GI tract, reduce cholesterol, monitor BGL and have a reduction of many cancers. **METABOLISM & THE LIVER** **Describe the process of glucose production?** The liver supplies sugar or glucose by turning glycogen into glucose in a process called glycogenolysis. **How does the hepatic portal circulation ensure the transfer of nutrients to the liver?** The hepatic portal circulation ensures the transfer of nutrients to the liver by collecting absorbed nutrients from the gastrointestinal tract and directing them to the liver for processing before they enter the general circulation **Basel Metabolic Rate** **What does "basal metabolic rate" mean?** The basal metabolic rate (BMR) refers to the body\'s rate of energy expenditure in basal conditions, which includes being awake but resting, in a postabsorptive state, and in a comfortably warm environment **What is the metabolic hormone?** Insulin. **When the external environment is cool/cold, the body responds by shivering. Do blood vessels dilate or constrict?** Blood vessels constrict in order to reduce blood flow to the skin and conserve heat within the core of the body
