What's developed as a result of the electron transport chain?
a. membrane potential
b. proton gradient
c. phospholipid bilayer
d. new cells

The result of electron transport chain is B. Photon Gradient.

The electron transport chain is a gathering of layer implanted proteins and natural atoms, the vast majority of them sorted out into four huge edifices named I to IV. In eukaryotes, numerous duplicates of these particles are found in the internal membrane of the mitochondria whereas, in prokaryotes, it is found in the plasma membrane.  

As the electrons travel through the chain, they go from a higher to a lower vitality level, moving from the region which is less eager for an electron to more eager for electron particles. Vitality is discharged in these "declining" electron moves, and a few of the protein buildings utilize the discharged vitality to release protons to the inner membrane space from the mitochondria, framing a proton gradient.
