Question

The electron transport chain (ETC), or respiratory chain, is linkedto proton movement and ATP synthesis. Select the STATEMENTS thatACCURATELY describe the electron transport chain.(True/False)
a)Electron transfer in the ETC is coupled to proton transfer formthe matrix to the intermembrane space.
b)Electrons generated by he citric acid cycle in the mitochondrialmatrix enter the ETC.
c)The outer membrane of mitochondria is readily permeable to smallmolecules and hydrogen ions.
d)Electron carriers in the mitochondrial matrix include ubiquinone(coenzyme Q), FMN, and cytochrome c.
e)Prosthetic groups, such as iron-sulfer centers, are directlyinvolved with electron transfer.
f)Electron carriers are organized into four complexes of proteinsand prosthetic groups.
g)The reactions of the ETC take place in the outer membrane ofmitochondria.
