CLEP Biology: Basic Chemistry

Subjects : clep, science, biology
Instructions:
  • Answer 40 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. Many sugars; complex carbs






2. The ability to do work






3. What is chief ingredient in living things?






4. Homogenous(alike) mixture of one or more substances in another substance






5. Affect the rate of the reaction but are not changed in the reaction






6. Dissolved






7. Can change between gel and sol phases (ex. protoplasm)






8. The living content in a cell






9. Energy in motion






10. The putting together of living things






11. Smallest unit of an element






12. Proteins only one that are...






13. Matter is composed of ______






14. The increase in randomness and loss of usable energy






15. In any process - energy is neither created nor destroyed






16. Elements essential to life






17. Dissolver (water: universal solvent)






18. Found in nucleus of cell; contain info necessary for the manufacture of an organism's proteins; nucleic acid form genes; watson and crick discovered






19. Group of organic substances slightly soluble in water; very soluble in other organic liquids; mostly structural but also store energy; humans and animals store their excess energy as lipids






20. Process of making two DNA molecules from one strand






21. Made of amino acids; polypeptide chain of amino acids; make up the majority of an organism's cells; used as enzymes or as building blocks






22. Made of nucleotides; sugar - phosphate - base; adenine - thyOOmine; guani`ne - cytosine






23. Absorbs heat; endo - within






24. Single sugars; glucose(C6H12O6) is a monosaccharide that is manufactured by plants in photosynthesis






25. Is a polysaccharide; stored by plants; a major energy source for humans; humans can't make it






26. Whenever energy is used - some of the energy is wasted






27. Double sugars; maltose - sucrose - lactose; formed when monosaccharides undergo dehydration synthesis - when a suger looses hydrozyl group (OH) and another gives hydrogen - resulting in a water molecule and a ...






28. Another nucleic acid; single strand; sometime replaces thymine






29. Organic compounds that contain carbon - hydrogen and oxygen; provide structure and store energy






30. Gives off heat; exo - outside






31. Stored energy






32. Most abundant form of lipids; building blocks for other lipids; have hydrophilic and hydrophobic ends; in water - will align themselves; good source of energy; found in dairy and animal tissues






33. When a cell needs a monosaccharide - enzymes cause disaccharides to undergo hydrolysis - which means the breaking down of a disaccharide by adding a water molecule






34. Particles are mixed but not dissolved






35. Polysaccharide; strong and flexible; makes up shells of crabs - lobsters - shrimp - insects; found in cell walls of fungi






36. Cannot change between gel and sol (ex. egg whites)






37. Composed of long chains of glucose; is a polysaccharide; found in plant cell walls; nondigestible by most animals; part of our diet called bulk or rubbage(fiber)






38. Mixture of fine particles that do not settle out quickly (ex. protoplasm)






39. Polysaccharide; animal starch (animals and humans eat starches abd break them down to monosaccharides; the liver converts them to glycogen for storage)






40. The diffusion of water(!!) through a semipermiable membrane; equilibrium is never reached.
