Question

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 Choose all that apply. Electron carriers are organized into four complexes of proteins and prosthetic groups Electron transfer in the ETC is coupled to proton transfer from the matrix to the intermembrane space Prosthetic groups, such as iron-sulfur centers, are directly involved with electron transfer Electron carriers in the mitochondrial matrix include ubiquinone (coenzyme Q), FMN, and cytochrome c. The outer membrane of mitochondria is readily permeable to small molecules and hydrogen ions The reactions of the ETC take place in the outer membrane of mitochondria Electrons generated by the citric acid cycle in the mitochondrial matrix enter the ETC One of your answers is incorrect, and there is another correct answer Electrons enter the ETC through electron donors such as NADH. Consider the origin of the NADH

Explanation / Answer

1,2,3,4,7

Note - the reaction of etc take place in inner mitrochondrial membrane .

The carrier of electron help in undergoing oxidation and reducaton .

Etc is linked atp symthase which pushes proton from matrix to inner membrane .
