oxidative phosphorylation/ ETC Flashcards
NADH passes its electrons to the ———- ————- ———, within the ——- mitocondrial membrane
transmembrane protein complexes
each step the electrons pass through each complex they complexes have a
higher affinity for the electron then the previous
atp couples what
the transport of H+s from the mitochondrial matrix to the inner membranous space
what do you generate a
electrochemical gradient across a highly impermeable membrane
complex 1
NADH - Q oxidoreductase complex 1
Q
ubiquinone
complex 3
Q - cytochrome c oxidoreductase complex 3
C
cytochrome c
complex 4
cytochrome c oxidase complex 4
how does FADH2 enter the ETC
through succinate Q reductase
succinate Q reductase contains the enzyme
succinate dehydrogenase
what is Q
it is a coenzme
how is H+ translocated
a series of confirmational changes where the complexes deposit H+ on the other side of the membrane
moving H+s across the membrane produces a electrochemical gradient or
proton motive force
the movement of H+ back into matrix does what?
rotates the spindle of atp synthase (rotor)
the rotor is ———– and cause confirmational changes in the subunit that makes up the ————-
asymmetric
stator
rotation can be demonstrated by an —— ———, is attached to the ———- of the ATP synthase
a ———– molecule is attached to the actin arm
actin filament
spindle
fluorescent
