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. The increase in randomness and loss of usable energy

2. Energy in motion

3. Smallest unit of an element

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

5. Particles are mixed but not dissolved

6. The ability to do work

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

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. The putting together of living things

10. Absorbs heat; endo - within

11. Elements essential to life

12. Gives off heat; exo - outside

13. Process of making two DNA molecules from one strand

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

15. Dissolved

16. 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

17. 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)

18. What is chief ingredient in living things?

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

20. 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 ...

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

22. 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

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

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

25. Stored energy

26. Dissolver (water: universal solvent)

27. Matter is composed of ______

28. Many sugars; complex carbs

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

30. Proteins only one that are...

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

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

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

34. The living content in a cell

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

36. 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

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

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

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

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