Adhesion
When water molecules stick to something else
Cohesion
When water molecules stick to each other
Surface Tension
When water molecules stick to each other (called cohesion and caused by polarity) to form a “skin” on the surface
Polarity (Polar Molecule)
Molecules with opposite charges on either end
Universal Solvent
Dissolves many things; if it dissolves in water, then you know it is polar
High Specific Heat
Takes a lot of energy to heat up
Expands When Frozen
example: potholes
Capillary Action
When water moves up tiny passages against the flow of gravity
organic
contains carbon
inorganic
does not contain carbon
monomer
building blocks
polymer
many monomers joined together
dehydration synthesis
The process of joining monomers (into polymers) by removing water
hydrolysis
The process of breaking polymers (into monomers) by adding water
elements of carbs
C, H, O
elements of proteins
C, H, O, N
elements of lipids
C, H, O
elements of nucleic acids
C, H, O, N, P
monomer of carbs
Monosaccharides
monomer of proteins
amino acids
monomer of lipids
fatty acids/glycerol
monomer of nucleic acids
nucleotides
function of enzymes
serves as a catalyst for (speeds up) chemical reactions
impacts of increasing temperature on enzyme activity
activity increases until a certain point, then becomes denatured and stops
