Molecules in cells
Water
Universal solvent
dissocation
solute molecules are pulled apart and surrounded by water molecules
only dissolve polar substances
Reactions only happen to broken down molecules
Solid water is less dense
crystal bond = solid water
isolates organisms in body of water
solid water has a lower PH level than 7 so it floats
protects organisms in a body of water
molecules are sticky
molecules are polar allowing molecules to stick (bond) together through hydrogen bonding
Cohesion: Like molecules bond together
Adhesion: Unlike molecules bond together
Cohesion and Adhesion are hydrogen bonding
Allows water to climb trees
Resists temperature change
How?
Hydrogen bonds have to stay together and once they break, they start to heat up
Gives organisms time to acclimate
absorbs heat from chemical reactions
Molecules are polar
polar = uneven
uneven distribution of charge
makes up all other properties
BOM
Lipids
monomer = fatty acid
saturated fatty acids
carbohydrate chains in animals
unsaturated fatty acids
carbohydrate chains in plants
Polymer =fat molecule
fatty acids bonded together
Proteins
monomer = amino acids
form polypeptide chains
polymer = polypeptides
macromolecule where more than one chain of amino acid is bonded together
Carbs
monomer = monosaccharides
Glucose
energy source of a cell
Fructose
sweet
Polymer = Polysaccharides
glycogen
storage of extra glucose in animals
cellulose
Main component of cell walls.
starch
storage of extra gluecose in plants
Nucleic Acids
Monomer = nucleotides
A - T
C - G
3 types
Phosphate group
Nitrogen base
Sugar
polymer = nucleic acids
DNA
carry gentic information
RNA
helps DNA
