Block Biology Unit 1 Review Guide Answers FALL 2010

1 • • Carbohydrates Lipids Nucleic Acids Proteins

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

3 • Carbon • Hydrogen • Oxygen

4 • Sugars & Starches

5 • To make energy

6 • Rice, pasta, bread, cake, sweets

7 • Amino acid

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

9 • Carbon • Hydrogen • Oxygen • Nitrogen

10 • Enzyme

11 • Antibody (pl: antibodies)

12 • In Ribosomes

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

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

15 • DNA & RNA

16 • Nucleotides

17 • Carbon • Hydrogen • Oxygen • Nitrogen • Phosphorus

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

19

20 • p. H changes • High temperatures • Salty environments

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

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.

23 • Hydrogen bonds

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

25 • 35 o. C • This is true because 35 o. C is the temperature where the most product was produced. • More active the enzyme is = the more product produced

26 • Prokaryote • Eukaryote

27 • Ribosome

28 • Golgi apparatus

29 • bacteria, plants, fungi and algae

30 • ALL CELLS!!!

31 • ALL CELLS!!!

32 • Eukaryotes = plants, animals, fungi, and protists

33 • plants, animals, fungi, and protists

34 • Bacteria (this is the only example!!)

35 • Mitochondria

36 • Chloroplast

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

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

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

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

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.
