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 putting together of living things

2. Stored energy

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

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

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

6. Matter is composed of ______

7. 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

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

9. Proteins only one that are...

10. Many sugars; complex carbs

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

12. The living content in a cell

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

14. Smallest unit of an element

15. Dissolved

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

17. The ability to do work

18. Dissolver (water: universal solvent)

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

20. Gives off heat; exo - outside

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

22. 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

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

24. 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 ...

25. The increase in randomness and loss of usable energy

26. 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

27. Absorbs heat; endo - within

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

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

30. Elements essential to life

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

32. Process of making two DNA molecules from one strand

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

34. Energy in motion

35. Particles are mixed but not dissolved

36. 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

37. 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)

38. What is chief ingredient in living things?

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
