4
monomers are building blocks of _________
polymers
electrons move ion nucleus in region called __________
electron clouds
what is the structure of a lipid?
3 fatty acid chains to glycerol backbone
what uses 1:2:1 ratio?
carbohydrates
what is taking place in condensation reaction?
OH & H groups are coming off and forming H2o, water molecule
why are enzymes important and where do they belong?
belong to protein and they are important because they speed up chemical reaction. different chemical reaction rate could help evolution, which could change life.
what is each ring called?
energy level
how many rings are in an e-cloud?
8
2 atoms of same element that have different # of neutrons
isotope
when is a covalent bond taking place?
when electrons are shared with atoms
what are main elements found in living organisms and which is most abundant?
carbon, oxygen, hydrogen, nitrogen, pohsphate, and sulfur
what is an compound that have same simple formula as other compounds but have different 3 d structures
isomer
what is a pos. ion?

" " neg. ion
cation

anion
what is a polar molecule?
molecule w\ un= distribution of charge
molecule
particle in which atoms are bonded by sharing electrons in covalent bonds
solution
1 or more sub. distributed evenly throughout another sub.
suspension
particles temp. mixed in solution
colloid
particles larger than in solution but smaller than in suspension
mixture
each molecule type retains its own properties when together w\ others
covalent bond
when 2 atoms share electrons what force holds them together
covalent bond
attractive force between 2 atoms share electrons the force that holds them together
compound
substance formed when atoms of different elements combine chemically
what happens in hydrolysis reaction?
breakin apart of molecule by = water. bonds between monomers inpolymers break down by = water.

h2o splits, h goes on 1 and oh goes on another
when ph of something lower?
concentration of hydrogen is greater
as the ph is higher concentration of what is greater?
hydroxide
at 0 what is the solution?
acidic
at 14 what is the solution?
basic
what are lipids made of?
carbon, hydrogen, oxygen
what are nucleic acids made of?
carbon, oxygen, hydrogen, nitrogen, phosphorus
what are carbphydrates made of?
carbon, hydrogen, oxygen
what are proteins made of?
carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur
what are nucleic acids used for?
to store info in code, carry out genetic info, makes DNA
what are carb. used for?
short term energy storage
what are lipids used for?
long term energy storage, creates cell membranes
ionic bond
attractive force between 2 ions of opposite charge
