| Question | Answer |
|---|---|
| The movement of digested food through the intestinal wall into the blood stream. | Absorption |
| A diet which contains all of the nutrients in the right proportion, opposite to unbalanced. | Balanced |
| A macronutrient; a group of organic chemicals containing carbon, hydrogen and oxygen atoms. Include large molecules of starch and small molecules like glucose. A source of chemical energy for organisms. | Carbohydrates |
| Cholesterol is a fatty substance found in the blood. It's mainly made in the liver, it is used in the construction of cell membranes. | Cholesterol |
| An organism which obtains its food by eating either producers or other consumers or both. | Consumer |
| A diet missing in a particular nutrient which leads to a specific set of symptoms eg lack of vitamin C leads to scurvy. | Deficiency disease |
| A disease where the pancreas fails to produce enough insulin so dangerously high levels of glucose exist in the blood and body fluids. | Diabetes |
| The process of breaking food down mechanically and chemically so it is more soluble and ready to be absorbed. | Digestion |
| Chemical catalysts which speed up biochemical reactions. They can be extra cellular eg digestive enzymes or intracellular eg catalyse. | Enzyme |
| Life processes which involves the removal of waste materials such as urea from the body. | Excretion |
| The system which is responsible for removing urine from the body. | Excretory |
| A macronutrient; Organic molecules constructed of chains of fatty acids with glycerol. A very energy rich nutrient source for organisms. | Fats |
| Organs in the body which manufacture hormones which are then secreted into the blood. | Glands |
| A simple sugar, rich in energy made by plants in their leaves, and used by animals as foo | Glucose |
| An unbalanced diet produces a person who may be overweight or underweight; or may have type 2 diabetes, or a deficiency disease. This person is said to be? | Malnourished |
| The rate at which all the chemical reactions in the cells of the body are carried out. | Metabolic rate |
| A micronutrient; required in small doses for a wide range of different structures and processes eg Calcium is used in the construction of bone, and Iron is needed in the haemoglobin molecule, Magnesium is needed in the chlorophyll molecule. | Mineral ions |
| Salts, compounds containing metal elements required by plants eg Iron, magnesium. | Minerals |
| Life processes whereby organisms obtain plants produce food, animals consume food plants and other animals. | Nutrition |
| An organ near the stomach which makes digestive enzymes and the hormone insulin. | Pancreas |
| A Macronutrient; Organic molecules constructed of chains of amino acids, contain carbon, hydrogen, oxygen and nitrogen atoms. Used in the construction of tissues by all organisms. | Proteins |
| Life processes where organisms release energy from their food | Respiration |
| A carbohydrate made up of glucose molecules linked together, it is insoluble | Starch |
| These are medicinal drugs which are prescribed to patients to lowering the risk of heart and circulatory diseases. | Statin |
| A micronutrient; Required in small doses for the a wide range of different structures and processes eg vitamin K for blood clotting, vitamin C for skin and gum tissue. | Vitamins |
| All the chemical reactions in the body. | Metabolism |
| A health condition that results from taking in too much energy. | Obesity |
| Health conditions genetically passed on from your parents. | Inherited factors |
| Food group used for storage, insulation and energy | Fats |
| Lost from the body as sweat, breath, faeces, and urine. | Water |
| Helps prevent constipation and bowel cancer. | Fibre |
| A waxy substance obtained in your diet and made by your liver that is needed for cell membranes and to make sex hormones. | Cholesterol |
| Drugs used to treat high cholesterol levels | Statins |
