The electron transport chain, or respiratory chain, is linked to proton movement and ATP synthesis. Select the statements that accurately describe the electron transport chain.

Choose ALL that apply (more than one correct answer):

A) Electron transfer in the ETC is coupled to proton transfer from the matrix to the intermembrane space.
B) The inner membrane of mitochondria is readily permeable to small molecules and hydrogen ions.
C) The reactions of the ETC take place in the inner membrane of mitochondria.
D) Prosthetic groups, such as iron-sulfur centers, are directly involved with electron transfer.
E) Electron carriers are organized into four complexes of proteins and prostheritc groups.
F) Electrons generated by the Citric Acid Cycle in the mitochondrial matrix enter the ETC.
G) Electron carriers in the mitochondrial matrix include ubiquinone (coenzyme Q), FMN, and Cytochrome C.
