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

2. 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

3. Stored energy

4. Absorbs heat; endo - within

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

6. Dissolver (water: universal solvent)

7. Proteins only one that are...

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

9. 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

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

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

12. Many sugars; complex carbs

13. Smallest unit of an element

14. What is chief ingredient in living things?

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

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

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

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

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

20. Process of making two DNA molecules from one strand

21. Elements essential to life

22. The ability to do work

23. 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

24. Dissolved

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

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

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. The increase in randomness and loss of usable energy

29. The living content in a cell

30. Gives off heat; exo - outside

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

32. The putting together of living things

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

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. Matter is composed of ______

36. Energy in motion

37. Particles are mixed but not dissolved

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

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. 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
