Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. An enzyme made in the ileum which breaks peptides into amino acids.






2. Eggs belong in this food group






3. Horizontal






4. Irreversible reaction - unfolding of the protein chain - caused by HEAT - ADDITION OF ACID & MECHANICAL ACTION.






5. Breaking down excess protein in the liver. Carboxyl group is converted to glycogen and stored as energy. Amino group is converted to ammonia then to urea and excreted as urine.






6. Globular proteins linked with other non-protein molecules.






7. Chemical substances that are needed in the body for correct functioning






8. Protein are formed as a result of chemical or enzymic action on the protein.






9. Amount of each nutrient that is needed to to meet a persons nutritional requirements.






10. 90 degrees of each other






11. Chemical reaction when 2 amino acids join together with the elimination of water. Amino group of one amino acid combines with the carboxyl group of another amino acid.






12. Substances that are important for the body's growth and care






13. Gives you healthy skin and eyes






14. 20g






15. Denaturing a protein (liquid to a solid) e.g. cooking an egg






16. The food that the nutrient is found in.






17. Protein found in wheat - gives elasticity to foods e.g bread (Coeliacs are allergic to it)






18. Contrast; opposite colors






19. Sugar in ripe fruit - starch in cereals - fibre in bran and celery.






20. Dark - leafy vegetables and orange vegetables are good sources of this vitamin






21. Catalyst that speeds up or slows down a reaction without being used up itself.






22. Low fat milk - non fat yogurt - and lite sour cream are low in this nutrient






23. Foods from the extras group are usually high






24. Vertical






25. 250g






26. The function / job of a nutrient in the body.






27. 20g






28. The process of breaking down food into a form the body can use






29. Where a food is missing one or more of the essential amino acids. They are usually plant foods.






30. Good sources of this vitamin are oranges - kiwi - and grapefruit






31. 9-11 servings daily






32. Should be eaten sparingly






33. Formed when a number of amino acids join together due to the formation of peptide links.






34. 180






35. 200






36. Vegetables are a great source of this






37. An enzyme made in the pancreas that travels to the duodenum and breaks peptones into peptides.






38. 175g






39. Describes the way an object surface looks and feels






40. Severe protein deficiency resulting in thin limbs - sunken face and pot belly. Occurs in 3rd World countries.






41. Keeps the body healthy protecting it from diseases such as scurvy (Vit. C) and rickets (Vit. D).






42. The building blocks that make up proteins - Smallest part of a protein






43. Helps body fight infection - helps wounds heal - helps keep gums healthy citrus fruits - berries - melon






44. Helps eyes adjust to darkness - protects lining of throat - nose and mouth and other organs from infection eggs - dark green veggies - deep yellow veggies and fruits






45. Diagonal






46. Built in a factory and installed at a specific site






47. A link formed during the condensation reaction when the amino group of one amino acid chemically combines with the carboxyl group of another amino acid with the loss of water molecule.






48. One hue






49. Helps build strong muscles and repairs body tissue






50. Helps regulate body fluids - helps muscles like the heart function orange juice - bananas
