B is the answer.

As reduction and oxidation (electron transfer), occurs simultaneously, protons (H+) are also transported across a membrane. The result is an electromagnetic proton gradient which in turn drives the synthesis of adenosine triphosphate (ATP), which is the molecule used for energy.

The result of the electron transport chain is B) Proton gradient.

What is the electron shipping chain?

The electron transport chain is a series of four protein complexes that couple redox reactions, developing an electrochemical gradient that ends in the introduction of ATP in an entire device named oxidative phosphorylation. It happens in mitochondria in both mobile breathing and photosynthesis.

What are the 3 fundamental steps in the electron transport chain?

The three main steps in the electron shipping chain are:

  • Generation of a proton gradient throughout the mitochondrial membrane. Proton accumulation happens inside the intermembrane space of mitochondria.
  • Reduction of molecular oxygen and formation of water.
  • ATP synthesis by means of chemiosmosis.

Hence the result of the proton gradient which is developed into the inter membrane of thylacoid or mitochondria due to H+ ions concentration.
