The electron transport chain (ETC), or respiratory chain, is linked to proton movement and ATP synthesis. Select the STATEMENTS that ACCURATELY describe the electron transport chain. (True/False)
a)Electron transfer in the ETC is coupled to proton transfer form the matrix to the intermembrane space. b)Electrons generated by he citric acid cycle in the mitochondrial matrix enter the ETC. c)The outer membrane of mitochondria is readily permeable to small molecules 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 directly involved with electron transfer. f)Electron carriers are organized into four complexes of proteins and prosthetic groups. g)The reactions of the ETC take place in the outer membrane of mitochondria.
