The electron transport chain's main purpose is to create a proton gradient, which Complex V can use to synthesize ATP.TrueFalse

The purpose of the electron transport chain is to A) Accumulate electrons to store energy B) Transfer electrons in order to generate ATP C) Donate electrons to change membrane potential D) All of the above

Explain the structural features of ATP suited to its role as an energy carrier

It functions as a molecular motor driven by the flow of protons, converting their energy into the synthesis of ATP from ADP and phosphate.

Cyclic electron transport enhances ATP production because?

The electron transport chain: A. involves four protein complexes (I, II, III and IV) all of which are proton pumps. B. Uses ubiquinol as a mobile electron transporter to deliver electrons to complex III. C. intersects with the Krebs cycle, because isocitrate dehydrogenase is the same as complex III. D. increases in the concentration of hydrogen ions in the mitochondrial matrix.
