1. Block Biology Unit 1 Review Guide Answers
FALL 2010

2. 1
Carbohydrates
Lipids
Nucleic Acids
Proteins

3. 2
A small molecule that, when put together with others, makes a larger molecule. Or
A molecular subunit of a polymer.

4. 3
Carbon
Hydrogen
Oxygen

5. 4
Sugars & Starches

6. 5
To make energy

7. 6
Rice, pasta, bread, cake, sweets

8. 7
Amino acid

9. 8 Fight infections Build bones & muscles Catalyze (speed up) reactions
Chemical messengers/transporters

10. 9
Carbon
Hydrogen
Oxygen
Nitrogen

11. 10
Enzyme

12. 11
Antibody (pl: antibodies)

13. 12
In Ribosomes

14. 13
Fats
Oils
Waxes
Steroids (ex: cholesterol, testosterone)

15. 14 Main function: Store energy Other smaller functions:
Make the cell membrane
Chemical messengers
Waterproofing

16. 15
DNA & RNA

17. 16
Nucleotides

18. 17
Carbon
Hydrogen
Oxygen
Nitrogen
Phosphorus

19. 18 It lowers the activation energy needed to start the reaction.
Less energy required = get job done faster

20. 19

21. 20
pH changes
High temperatures
Salty environments

22. 21
An unequal sharing of electrons between a large molecule (like oxygen) and a small molecule (like hydrogen).

23. 22
Because the oxygen in a water molecule can pull on the electrons with a greater force than both of the hydrogens can.
So, the oxygen becomes slightly negative and the hydrogens become slightly positive.

24. 23
Hydrogen bonds

25. 24 Cohesion Adhesion Capillary action Surface tension
High specific heat
High heat of vaporization
Solvent abilities
Density

26. 25
35oC
This is true because 35oC is the temperature where the most product was produced.
More active the enzyme is = the more product produced

27. 26
Prokaryote
Eukaryote

28. 27
Ribosome

29. 28
Golgi apparatus

30. 29
bacteria, plants, fungi and algae

31. 30
ALL CELLS!!!

32. 31
ALL CELLS!!!

33. 32
Eukaryotes = plants, animals, fungi, and protists

34. 33
plants, animals, fungi, and protists

35. 34
Bacteria (this is the only example!!)

36. 35
Mitochondria

37. 36
Chloroplast

38. 37
It decides what gets to come in/go out of the cell.

39. 38
It controls the cell just like a mayor controls the city.

40. 39
It give the cell internal support and structure, just like our skeleton does.

41. 40
It stores food & water, just like a pantry.

42. 41 1.) All living things are made of cells.
2.) The cell is the basic unit of structure of living things. (Anything smaller than a cell is not living.)
3.) All cells come from other existing cells.
