Verified step by step guidance

Understand the role of the electron transport chain (ETC) in cellular respiration. The ETC is a series of protein complexes located in the inner mitochondrial membrane that transfers electrons from electron donors to electron acceptors via redox reactions.

Recognize that the primary purpose of the ETC is to create a proton gradient across the inner mitochondrial membrane. This gradient is used to drive the synthesis of ATP through a process called oxidative phosphorylation.

Identify the high-energy molecule that is synthesized as a result of the proton gradient created by the ETC. This molecule is adenosine triphosphate (ATP), which is the main energy currency of the cell.

Consider the role of other molecules listed in the problem. NADH and FADH2 are electron carriers that donate electrons to the ETC, but they are not the primary high-energy molecules formed by the ETC.

GTP is another high-energy molecule, but it is primarily formed in the citric acid cycle, not directly by the ETC. Therefore, the primary high-energy molecule formed by the electron transport chain is ATP.
