The name of process of aerobic respiration, in which energy is provided in steps in electron transport chain, is :

  • EMP-pathway

  • decarboxylation

  • photophosphorylation

  • oxidative phosphorylation


D.

oxidative phosphorylation

An electron transport chain (ETC) is a series of complexes that transfer electrons from electron donors to electron acceptors via redox (both reduction and oxidation occurring simultaneously) reactions, and couples this electron transfer with the transfer of protons (H+ ions) across a membrane.

The efficiency of oxidative phosphorylation is 40% higher than any other energy conversion system. It is one of the key processes in respiration in which the energy extracted from food is trapped and made available to the living cells.
