Find the correct statement(s): (i) The electron transport proteins contain Cu and Fe metals. (ii) For efficient electron transport, both the Gibbs energy and the reorganization energy have to be low. (iii) Electron transport chains exist only in organisms that use O₂ as oxidizing agent.

Question

Quizplus · Accepted Answer

(i) The electron transport chain (ETC) indeed contains proteins with metal centers, including copper (Cu) and iron (Fe), which are crucial for the transfer of electrons through the chain. (ii) For efficient electron transport, it is necessary for both the Gibbs energy (ΔG) to be favorable (negative) for the reaction to proceed spontaneously and the reorganization energy to be low to facilitate efficient electron transfer between molecules.
