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. 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






2. Proteins only one that are...






3. The ability to do work






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






5. Many sugars; complex carbs






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






7. The putting together of living things






8. What is chief ingredient in living things?






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






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






11. Particles are mixed but not dissolved






12. Smallest unit of an element






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






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






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






17. Energy in motion






18. Elements essential to life






19. Dissolver (water: universal solvent)






20. Stored energy






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






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






23. Absorbs heat; endo - within






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






25. Dissolved






26. Matter is composed of ______






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






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






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






31. 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






32. Gives off heat; exo - outside






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






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






35. The living content in a cell






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






37. 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






38. The increase in randomness and loss of usable energy






39. 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






40. Process of making two DNA molecules from one strand
