Question
(Electron transport & ATP synthase)
Which of the following statements is FALSE?
Cytochrome c and coenzyme Q are both soluble electron carriers that are loosely attached to the outside of the inner mitochondrial membrane.
During electron transport protons are pumped across the inner mitochondrial membrane from the matrix to the intermembrane space.
All of the protein complexes of the mitochondrial respiratory chain are bound in the inner mitochondrial membrane.
The citric acid cycle is linked directly to the mitochondrial respiratory chain at the site of complex II.
Oxygen is reduced to water at complex IV of the mitochondrial respiratory chain.
Explanation / Answer
Cytochrome c and coenzyme Q are both soluble electron carriers that are loosely attached to the outside of the inner mitochondrial membrane.
CoQ is fat solule, and thus, is mobile in the cell membranes. It acts as a carrier of electons from complex I and complex II to complex III. CoQ is the only molecule that can perform this task. It is found on the inner membrane of the mitochondrion.
CytC is water soluble and is loosely associated with the inner membrane of the mitochondrion.
