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. Stored energy






2. Energy in motion






3. 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






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






5. The putting together of living things






6. Particles are mixed but not dissolved






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






8. What is chief ingredient in living things?






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






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






11. Absorbs heat; endo - within






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






13. Smallest unit of an element






14. Matter is composed of ______






15. 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)






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






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






18. Process of making two DNA molecules from one strand






19. Many sugars; complex carbs






20. Elements essential to life






21. Gives off heat; exo - outside






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






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






24. 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 ...






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






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






27. Dissolver (water: universal solvent)






28. Dissolved






29. 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






30. Proteins only one that are...






31. The ability to do work






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






33. 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






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






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






36. 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






37. The increase in randomness and loss of usable energy






38. The living content in a cell






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






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