- 1Intramolecular vs IntermolecularIntra- occurring between molecules (covalent, ionic)
Inter- occurring between atoms of different molecules (hydrogen bonds) - 2Why is water polar?Electrons are not shared equally, unpaired electrons and positive and negative charged ends
- 3Waters 8 Important PropertiesCohesion (attract to itself)
Adhesion (attract to other surfaces)
Capillarity (travel up a tube)
High specific heat
High heat of vapourization
Solid water less dense than liquid
Solvent
Transparent - 4What atoms are carbohydrates and lipids made up of?C, H and O
- 5Why are carbs well suited for energy storage?Many C-H bonds
- 6Examples of monosaccharides, disaccharides and polysaccharidesMono- glucose, fructose galactose
Di- lactose, maltose, sucrose
Poly- starch, cellulose, glycogen, pectin - 7Blood sugar levels are regulated by the ____ under the hormonal control of the _____1. Liver
2. Pancreas - 8Dehydration Synthesis vs HydrolysisDehydration Synthesis- joining two molecules by removing water
Hydrolysis- Breaking apart two molecules by adding water - 9What are lipids made up of?Glycerol and 3 fatty acids
- 10Unsaturated vs saturated fatsUnsaturated has double bonds and saturated does not. Unsaturated are liquid, saturated are solid.
- 11What atoms are proteins made up of?C, H, O, N and S
- 12Primary, Secondary, Tertiary and Quaternary Structure of ProteinsPrimary- basic protein sequence
Secondary- 3D structure with hydrogen bonds that causes formation of helix
Tertiary- folds itself
Quaternary- 2 or more have combined - 13Competitive vs Non- competitive inhibitionCompetitive- inhibitor goes to the active site so that substrate can not fit in
Non- competitive- inhibitor goes to allosteric site which changes the shape of the enzyme - 14What are the three type of integral proteins?Marker- nametag of cell
Transport- Shipping and receiving. Allows for active transport
Receptor- communication office of cell - 15What manufactures ribosomes?Nucleus
- 16What is the gel like fluid in the cytoplasm called?Cytosol
- 17Where does cellular respiration take place?Mitochondria
- 18How do ribosomes help to make amino acids?The plan for the amino acids are sent out of the nucleolus which pass through the ribosomes where the plan is read and they are assembled in proper sequence.
- 19What does the Golgi Apparatus do?Plans and organizes where the materials are going. Vesicles are formed here
- 20What is another name for a lysosome?Suicide Sac- because it releases digestive enzymes to destroy the cell when it is no longer functioning
- 21How thick is the average cell wall?7nm
- 22How does cell membrane maintain fluidity?Temperature- higher the temps mean more fluid
Double bonds in tails- helps keep tails less tightly packed
Tail Length- shorter tails mean more fluid
Cholesterol- breaks tightly packed phospholipid head - 234 Factors that Determine Rate of DiffusionSteepness of Gradient- bigger the difference, faster the diffusion
Temperature- high temperature= faster (more kinetic energy)
Surface Area- bigger surface area means faster diffusion (more molecules at once)
Type of Molecule- Small and non-polar= faster - 24Hypotonic vs Hypertonic vs IsotonicHypo- more inside the cell
Hyer- less inside the cell
Iso- equal
