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.

I had teo answers and both of them were wrong. here are my 2 attempts.

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. The outer membrane of mitochondria is readily permeable to small molecules and hydrogen ions. Electron carriers in the mitochondrial matrix include ubiquinone (coenzyme Q), FMN, and cytochrome c. 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. Electrons generated by the citric acid cycle in the mitochondrial matrix enter the ETC. Electron carriers are organized into four complexes of proteins and prosthetic groups The reactions of the ETC take place in the outer membrane of mitochondria Two of the answers you chose are incorrect Keep in mind that electron carriers undergo oxidation and reduction. Consider the location of these reactions in the ETC In addition, you may need to reconsider the location of the electron transfer reactions.

Explanation / Answer

In the second attempt of yours option one in not correct please uncheck it and option 5 is the correct one and the remaining you have marked are correct. As electrons generated by TCA in mitochondria actually goes to ETC.
