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






2. Matter is composed of ______






3. The ability to do work






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






5. 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






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






7. Many sugars; complex carbs






8. 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)






9. Particles are mixed but not dissolved






10. Gives off heat; exo - outside






11. Elements essential to life






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






13. Stored energy






14. 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






15. 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






16. The increase in randomness and loss of usable energy






17. 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






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






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






20. The living content in a cell






21. Dissolver (water: universal solvent)






22. The putting together of living things






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






24. Absorbs heat; endo - within






25. Smallest unit of an element






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






27. Proteins only one that are...






28. Energy in motion






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






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






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






32. Dissolved






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






34. 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 ...






35. Process of making two DNA molecules from one strand






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






37. What is chief ingredient in living things?






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






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






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