 Components of Nutrients:   Nutrients and their importance: ●        Carbohydrates - found in foods such as pasta, rice and potatoes; carbohydrates are used as a source of energy in respiration in cells. ●        Fats - found in fatty meats, cheese and butter. Fats have a variety of roles in organisms including insulation, energy, waterproofing, structure and protection around delicate organs. ●        Protein - found in meat, fish and eggs. Proteins are broken down into amino acids in digestion and absorbed into the blood. They are then used in cells to produce new proteins by protein synthesis, where they are used as enzymes in reactions and for structure. They can also be used for signalling as hormones, and carrying other molecules, for example haemoglobin which carries oxygen in the blood.   ●        Vitamins (C and D) - Vitamin C is found in citrus fruits and some other vegetables and is used in the synthe
