Across
  1. 3. positive for Benedict's reagent test
  2. 9. increase surface area for absorption (finger-like)
  3. 10. creating large molecules from small monomers
  4. 14. equal, no net movement (how we want our plasma to maintain homeostasis)
  5. 15. contains chlorophyll & starch grains, traps energy for photosynthesis
  6. 18. random movement of particles, passive process that uses no energy to take place
  7. 19. the net movement of water molecules from a region of high WATER POTENTIAL to a region of low WATER POTENTIAL
  8. 20. more than two sugars
  9. 21. breaking down big molecules to monomer parts
  10. 24. test for reducing sugars
  11. 28. glucose in molecule form
  12. 30. proteins (periodic table)
  13. 31. muscular tube that transports food from moth to stomach
  14. 33. larger structures made up of repeating monomer structures
  15. 34. the polysaccharides
  16. 37. intestine that recovers WATER and nutrients
  17. 39. tough, dead layer made of cellulose, prevents cell from bursting and allows water/salt to pass
  18. 40. made of 20 amino acids... (also their breakdown is urea)
  19. 41. random movement of particles from a region of high concentration to a region of low concentration
  20. 42. small structures attached to membranes/free and contain protein synthesis
  21. 45. is the oval structure contains DNA, controls activities/development
  22. 46. positive for DCPIP also colourless
  23. 47. membrane controls what enters/exits the cell, bc it's partially permeable, seperates internal from external chem
  24. 48. 1 sugar (monomers for carbohydrates)
  25. 49. the movement of particles through a cell membrane from a region of lower concentration to a region of higher concentration using energy from respiration
  26. 50. three fatty acid molecules bonded to a glycerol molecule through ester bonds
  27. 51. the active site of a enzyme is -------- to the substrate that reacts with it
Down
  1. 1. test for proteins
  2. 2. protease enzyme that breaks down proteins, produced in stomach
  3. 4. two sugars
  4. 5. found in cytoplasm, responsible for aerobic respiration
  5. 6. lower water potential outside the cell
  6. 7. the monosaccharides
  7. 8. molecules which can react with the enzyme
  8. 11. higher water potential inside cell (burst)
  9. 12. test for starch
  10. 13. fluid filled space with membrane, contains salts and sugars, and maintains turgor cell
  11. 16. what forms for positive fat/lipid test
  12. 17. the disaccharides (only one glucose)
  13. 18. produced by liver, stored in gallbladder, emulsifies (mixture that doesn't really blend) fats in small intestine
  14. 22. the bigger the difference, the faster the rate of diffusion
  15. 23. produces most enzymes secreted into small intestine
  16. 25. test for vitimin C
  17. 26. carbs/ fats (periodic table)
  18. 27. salivary ---- chemically breaks down carbohydrates in the mouth
  19. 29. jelly-like with organelles in it, the site of metabolic reactions
  20. 32. positive biuret test
  21. 35. test for fats/lipids
  22. 36. are proteins that function s biological catalyst
  23. 38. molecules we get at the end
  24. 43. positive for iodine solution test
  25. 44. smaller structures (molecule) which makes up larger chemical structures
