is able to diffuse to the next active site in a sequential manner.
Which of the following enzymes catalyzes a reaction of the citric acid cycle that
does NOT produce reduced electron carriers? - Succinyl-CoA synthetase
All of the enzymes of the citric acid cycle are located in the mitochondrion. -
True
The citric acid cycle is classed as a reductive pathway as it produces reduced
electron carriers. - False
Acetyl CoA is a feed forward activator of the enzyme ________ ensuring
sufficient oxaloacetate for the citric acid cycle to continue. - Pyruvate
carboxylase
Taking one mole of glucose through glycolysis and the citric acid cycle
generates: - 6C02, 10 NADH/H+, 2FADH2 and 4 ATP.
ATP synthase can produce ATP using as a direct energy source: - Energy from a
proton gradient established across the inner mitochondrial membrane
Which of the following is correct concerning the mitochondrial ATP synthase? -
It catalyzes ATP synthesis by a rotational catalysts mechanism
, During oxidative phosphorylation, the proton motive force that is generated by
electron transport is used to: - drive the synthesis of ATP as protons flow
passively back into the matrix through a proton pore assiciated with ATP
synthase
Which of the following statements is FALSE?
-All of the protein complexes of the mitochondrial respiratory chain are bound
in the inner mitochondrial membrane
-Cytochrome c and coenzyme Q are both soluble electron carriers that are
loosely attached to the outside of the inner mitochondrial membrane.
-Oxygen is reduced to water at complex IV of the mitochondrial respiratory
chain.
-During electron transport protons are pumped across the inner mitochondrial
membrane from the matrix to the intermembrane space. - Cytochrome c and
coenzyme Q are both soluble electron carriers that are loosely attached to the
outside of the inner mitochondrial membrane.
Which of the following is NOT an electron acceptor in the mitochondrial
respiratory chain?
CoQH2
FMN
