cell theory :




·
1) all living things are comprised of cells


2) all cells come from other cells


prokaryote


-
bacteria ,
archaed

-
more primitive

-
have nucleoid but no nucleus/organelles

eukaryotes :




-
all others


-
membrane-bound nucleus

~
other organelles


& Il :




-
cell membrane

- It chromosome/ribosome

↳
makes proteins

peroxisome-catch excess H202 Cundrogen peroxide (


lysosome digestive enzymes "e"

,

phylogenetic tree of life

last universal common ancestor


prokaryotes -
enbacteria

~
"true" bacteria

~ decomposers

~ some benign ,
others pathogenic (salmonella , ecoli ,
etc .



prokaryotes -
archaebacteria

~ "archaea"

~ salt/temp loving (not springs ,
salt ponds , etc . )

eukaryotes


~
from protists (1-cell) & algde .
plants & animals

enzymes :




~ lower activation energy fa

- usually proteins

-
not consumed

~
only works with specific substrate

~ fits into "active site"


rates of reaction : concentration or enzymes & substrates

~
temp helps until it denatures enzyme


diffusion

~
net movement of particles from night low concentrated dreas

-
follows and law of thermodynamics

& iffusion across membranes
