1. Given MRS GREN is an acronym for features of a living thing. Define Nutrition in our context study.
The process of providing or obtaining the food necessary for health and growth.
2. Make a table that lists the chemical elements in Carbohydrates | Carbon
Oxygen
Hydrogen | Fats | Stearic acidPalmitic acidOleic acid | Proteins | Sulphur carbon hydrogen oxygen nitrogen |
3. Briefly describe how large molecules are made from smaller basic units.
4. Make a table for the outcomes of these tests Substance | Test | Outcome | Starch | Iodine solution | If starch is present it will go Black/Blue | Sugar | Benedict’s Solution | when added to glucose and heated, turns brownish-orange | Protein | Biuret Test | The intensity of the colour is directly proportional to the concentration of a substance in a solution. Therefore if the colour was red there would be more protein. | Fats | Ethanol | If fats are present the paper it has been placed on will be translucent |
5. Describe the importance of this substance;
Substance | Importance | Carbohydrates | Body’s main energy source. Every gram of carbohydrates you consume contains about 4 calories. When you consume carbohydrates, the enzyme amylase converts them into glucose, the primary fuel that the body uses to power all cellular activity | Fats | The fats in your diet allow you to absorb the fat-soluble vitamins, which include vitamins A, D, E and K, and promote normal growth and development. | Proteins | They are essential for body structure, they help transfer things around the body | Vitamin C | Boosts immune system, boosts the cardiovascular system and prevents more serious illnesses in the future | Vitamin D | Vitamin D promotes calcium absorption in the gut | Calcium | Calcium is needed for good teeth and strong bones and for the proper function of nerves, muscles, kidneys, and the heart. | Iron | As oxygen
