Which of the following is more encompassing?
A) Electron transport chain
B) Oxidation phosphorylation
C) They are both the same
Ans:- They are both the same
In general terms we ETC AND OXIDATIVE PHISPORYLATION MEANS THE SAME THING.
When these electrons are used to reduce molecular oxygen to water, a large amount of free energy is liberated, which can be used to generate ATP. Oxidative phosphorylation is the process in which ATP is formed as a result of the transfer of electrons from NADH or FADH 2 to O 2 by a series of electron carriers
Oxidative phosphorylation is made up of two closely connected components: the electron transport chain and chemiosmosis.
In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient.
Chemiosmosis is the movement of ions across a semipermeable membrane, down their electrochemical gradient. An example of this would be the generation of adenosine triphosphate (ATP) by the movement of hydrogen ions (H+) across a membrane during cellular respiration or photosynthesis.
