CLEP Biology: Basic Chemistry

Subjects : clep, science, biology
Instructions:
  • Answer 40 questions in 30 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. 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 ...






3. Elements essential to life






4. 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






5. The ability to do work






6. The living content in a cell






7. What is chief ingredient in living things?






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






9. Proteins only one that are...






10. Particles are mixed but not dissolved






11. Stored energy






12. Many sugars; complex carbs






13. Absorbs heat; endo - within






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






15. Dissolver (water: universal solvent)






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






17. Matter is composed of ______






18. Process of making two DNA molecules from one strand






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






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






21. 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)






22. The putting together of living things






23. Energy in motion






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






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






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






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






28. The increase in randomness and loss of usable energy






29. 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






30. Gives off heat; exo - outside






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






32. 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






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






34. Dissolved






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






36. Smallest unit of an element






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






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






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






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