Verified step by step guidance

Begin by understanding the role of the electron transport chain (ETC) in cellular respiration. The ETC is a series of protein complexes and other molecules that transfer electrons from electron donors to electron acceptors via redox reactions.

Identify the components of the ETC. The main complexes involved are Complex I, II, III, and IV. Additionally, there are mobile electron carriers that shuttle electrons between these complexes.

Recognize the function of NADH and FADH2. These molecules are electron donors that provide electrons to the ETC, but they are not mobile carriers themselves.

Focus on the mobile electron carriers within the ETC. Coenzyme Q (CoQ) and cytochrome c (Cyt c) are the key mobile carriers that transport electrons between the complexes. CoQ transfers electrons from Complex I and II to Complex III, while Cyt c transfers electrons from Complex III to Complex IV.

Conclude by understanding that CoQ and Cyt c are the correct mobile electron carriers in the ETC, facilitating the transfer of electrons between the complexes to ultimately drive ATP synthesis.
