Complexes Flashcards
NADH-coenzyme Q reductase
C1
NADH dehydrogenase complex
C1
NADH oxido-reductase
C1
Succinate-coenzyme Q reductase
C2
Succinate dehydrogenase complex
C2
Coenzyme Q-cytochrome c reductase
C3
Cytochrome reductase
C3
Q-cytochrome oxidoreductase
C3
Cytochrome c oxidase
C4
A heme and copper containing complex
C4
ATP SYNTHASE COMPLEX (oxidation phosphorylation)
C5
much smaller than complex I and contains only four subunits
C2
TRUE / FALSE:
Two electron carriers, coenzyme Q and coenzyme A, which are not tightly associated with any of the four complexes, serve as mobile electron carriers that shuttle electrons between the various complexes
FALSE, coenzyme Q and cytochrome c
used to process the FADH2 that is generated in the citric acid cycle when succinate is converted to fumarate
C2
source for the electrons that are processed through complex I
C1
the fi nal recipient of the electrons from FADH2, with iron–sulfur proteins serving as intermediaries
C2
the largest of the four protein complexes
C1
contains 11 different subunits
C3
contains more than 40 subunits, including the B vitamin-containing fl avin mononucleotide (FMN) and several iron–sulfur proteins (FeSP)
C1
how many subunits does Complex III have?
11
how many subunits does complex I have?
more than 40 subunits
a hemecontaining protein in which reversible oxidation and reduction of an iron atom occur
cytochrome
lipid soluble and can move laterally within the mitochondrial membrane
Coenzyme Q
TRUE / FALSE:
All further redox reactions at complex III involve only electrons, which are conveyed further down the enzyme complex chain
TRUE
