define biology the study of life
1. order - cells are the basic units of life
2. sensitivity or response to the environment
3. reproduction
characteristic of life on 4. adaptation
earth 5. growth and development
6. regulation/homeostasis
7. energy processing
8. evolution
anything that takes up space and has mass (solid,
define matter
liquid, gas)
atomic number the number of protons (top corner)
mass number number of protons and neutrons (bottom corner)
cation positively charged ion
anion negatively charged ion
oxidation release of electron (OILRIG)
reduction accepting electron (OILRIG)
molecule same atoms bound together
compound atoms of different elements bound together
form by the attraction between oppositely charged
ionic bonds
ions
covalent bonds form by electron sharing
polar covalent created by unequal electron sharing
, 1. cohesion and adhesion
key functions of water 2. high specific heat
that influence life 3. density differences based on state
4. universal solvent
"water is sticky" hydrogen bonding allows water
cohesion and adhesion molecules to stick to one another (cohesion) and to
other surfaces (adhesion), making them wet
it takes a long time for water to heat and a long time
high specific heat for it to cool down (this is why water is a liquid at a
wide range of temperatures)
when water freezes the binds between the water
molecules become rigid and expand increasing the
density differences
overall volume of the water, this makes ice less
dense than liquid water and why ice floats
what is pH measure of concentration of H+ in a solution
macromolecules are all made of smaller units
monomers single subunits, building blocks
larger molecules made with 2 or more monomers,
polymers
bound with covalent bonds
anabolic reaction process of building bigger molecules from smaller
(dehydration) ones, "to put together while losing water"
process of breaking bigger molecules to form
catabolic reaction
smaller ones, "lysis" means to break, use water to
(hydrolysis)
break a bond
groups of atoms that occur within molecules and
functional groups confer specific chemical properties to those
molecules
hydroxyl group aka alcOHol
carbonyl group double bonded carbon and oxygen
carboxylic acid group combination of hydroxyl and carbonyl
amino group nitrogen
sulfhydryl/thiol group sulfur
, phosphate group phosphate
contain long chains of carbon atoms bonded to one
fatty acids
another and to hydrogen atoms
four connected carbon rings, cholesterol is a sterol
that's an important component of cell membranes,
sterols
other sterols may be hormones or color-inducing
pigments
aka fat, have three fatty acid chains attached to a
glycerol molecule, fats store large amounts of
triglycerides
energy and also provide padding and thermal
insulation
have two fatty acid chains and a phosphate group
phospholipids attached to a glycerol molecule, phospholipids are
an important component of cell membranes
unsaturated fats with trans-double bonds instead of
what is a trans-fat
cis-double bonds
phospholipid membrane what separates cells from everything else
denatured when a protein loses its natural shape
when a protein is d.) denatured
unfolded it is said to be
______?
a.) active
b.) inactive
c.) hydrolyzed
d.) denatured
e.) working
1. microtubules
cytoskeleton consists of 2. intermediate filaments
3. microfilaments
made with actin, aid in cell rigidity, allow cells to
quickly change shape and move, cell movement,
microfilaments
cell division, move organelles, cytoplasmic
streaming
