CLEP Biology: Basic Chemistry

Subjects : clep, science, biology
  • 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. Matter is composed of ______

2. Dissolved

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

4. Particles are mixed but not dissolved

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

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

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

8. 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

9. Elements essential to life

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

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

12. What is chief ingredient in living things?

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

14. Process of making two DNA molecules from one strand

15. The living content in a cell

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

17. Smallest unit of an element

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

19. 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

20. The putting together of living things

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

22. Stored energy

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

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

25. Energy in motion

26. Dissolver (water: universal solvent)

27. 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)

28. 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

29. Proteins only one that are...

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

31. Absorbs heat; endo - within

32. The increase in randomness and loss of usable energy

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

35. Gives off heat; exo - outside

36. The ability to do work

37. 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 ...

38. Many sugars; complex carbs

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

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