CLEP Biology: Chemistry Of Biology

Subjects : clep, science, biology
  • Answer 50 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 result of a chemical reaction.

2. Results of the structure of atoms and their interactions with each other.

3. A type of carbohydrate

4. When four or more monosaccharide's combine.

5. Six carbon sugars. The most commone monosaccharide. They are usually ring shaped.

6. Made of Carbon - hydrogen - and oxygen. The Ratio of H and O is always 2:1. Just like water.

7. When two or more atoms form a unique substance via a chemical bond. Water is an example.

8. When threee monosaccharide's combine.

9. When a compund breaks apart and forms a new compund with a free reactant.

10. Ribonucleic acid. Generally a single strand

11. Long term energy storage.

12. What is the strongest chemical bond?

13. An atom that has the same number of protons and electrons.

14. Deoxyribonucleic acid. Two strands that pair up via a hydrogen bond. They form a double helix shape.

15. The bond that holds monmers together to form polymers.

16. The amount of energy in a electron cloud. The weakest level is the shell closest to the nucleus. As the shell gets stronger more electrons may fill it. Electron fill the shell closest to the nucleus.

17. Provide a moisture barrier.

18. A single amino acid

19. Molecules that have regions of a partial charge. Water molecules have a positive hydrogen charge.

20. The last shell of the electron cloud. Atoms are more stable when this shell is full.

21. The double helix model of DNA.

22. Another name for proteins. Nameds this because of the peptide bonds that monomers use to connect together.

23. That matter and energy is neither created nor destroyed.

24. Neutral charged particles in the nucleus of an atom.

25. Sugare molecule in DNA

26. Contain Carbon - Hydrogen - Oxygen - Nitrogen - and sometimes sulfur and phospoirus. 20 common amino acids that make thousands of different proteins.

27. DNA and RNA. These are polymers (proteins)

28. Form components of cel membranes.

29. Connected monomers (Amino Acids).

30. A substance that can't be broken down into any other substance. The simplest form of an element is an atom.

31. The reacting molecules of a chemical reaction.

32. A compund that is able to dissolve many types of organic and inorganic compunds

33. All reaction spread energy which tend to diminish it's availability.

34. When two monosaccharide units form together. Glucose and fructose make table sugar. A water molecule is liberated when one is formed.

35. Compounds that contain carbon.

36. When positive and negative ions are attracted to each other. Weaker than a covalent bond. Table salt is an ionic bond.

37. Contain hydrogen - oxygen - nitrogen - sulfur - phosporus - and some metal ions.

38. A substance that changes the speed of a reaction. The catalyst is not affected at all during this reaction. All catalyst end in -ase.

39. A chemical bond between atoms when they share electrons between their valence shells. These are the strongest chemical bonds.

40. A polysaccharide made of joined glucose units. Used by many animals for short term energy. Found in muscle and liver tissue.

41. A chemical that accepts protons when dissolved in water. Above 7 on the pH scale.

42. Sugar molecule in RNA

43. The basic sugar unit.

44. Center of an atom. The number of protons in the nucleus is the same as the atomic number on the periodic table of elements.

45. Acids and bases. When combined in water they produce water and a salt (ionic compound)

46. A special protein. It functions as a catalyst for reactions

47. The force of attraction between water molecules that hold them together . A weak chemical bond.

48. When two or more molecules react with each other to form one or more moleculte types.

49. Negative charged particles of an atom. They orbit the nucleus. They have much less mass than protons and neutrons.

50. Most common starch in a plant cell. It is a long chain of water insoluable polysaccharides
