Hydrophobic force
when water encounters a nonpolar molecule
What do plants have that animals don't?
chloroplasts, glyxosome
glyxosome
stores fat as oil
myosin
allows motor movement along microfilament
eukaryotic heterotroph
has mitochondira, no chloroplast
hetertroph vs autotroph
hetero = consumer, auto= uses air, co2, etc
eukaryot v. prokaryot
eu= complex, has cytoskeleton, nucleus

pro= simple, no nucleus, no membranes
cytoskeleton
cytoplasm, protects cell
filaments
maintain form, tension
microtubule
transport
key parts of cytoskeleton
filaments, microtubule
golgi apparatus
processes protein and lipids
peroxisome
metabolise fatty acids (eukartot)
facilitated diffusion
molecules diffuse across membranes
active transport
transfers biochemicals via membranes
cholera treatment works because...
secondary active transport is still functioning
transport of Na+ from our intestine into our blood is source for
Na+, Ka+, ATPase
allosteric enzyme
changes shape, conformation
competitive inhibitor
prevents binding, decreases activity
passive v active transport
passive does not require chemical energy
active transport v facilitated diffusion
active can move across a concentrated gradient
gap v tight junction
allow the exchange of small molecules between cells

v exclude the passage of water molecules between cells
desmosome
maintain tissue form and strength
dynein
converts atp to movement
kinesin
motor protein, polar
actin
globular protein
protein kinase
adds phoshpate, changes enzyme activity
peptide bond
carboxyl group bonds to amino group
polypeptide
group of many amino acids
endoplasmic reticulum
protein tanslation, folding, and transport
archaebacteria
single cell, no nucleus
protozoa
single celled eukaryot
lysosome
digestion
hypertonic
higher solute concentration than inside cell
