The protons that are generated during the electron transport chain are generated by:
Hydrolysis reactions
Dehydration reactions
Oxidation reactions
Reduction reactions
Homework Answers
Option 3rd that is oxidation reactions is the correct answer. During electron transport chain, electrons are carried by NAD+ and FAD in the form of NADH and FADH2. NADH and FADH2 submit their electron to the electron at the beginning of the transport chain and converts into NAD+, H+ and 2 free electrons. Free electrons and H+ finally received by oxygen leading to formation of water molecule. Thus, H+ is formed by oxidation of NADH and FADH2 (hydrogen ion and electrons are removed from NADH and FADH2).
Note: Removal of electrons or hydrogen is known as oxidation.

The electron transport chain consists of protein complexes embedded in the inner mitochondrial membrane, where it generat a proton gradient by a series of oxidation-reduction, or redox, reactions. Although all of the stages of cellular respiration (glycolysis, the citric acid cycle, and the electron transport chain) are necessary for life, the electron transport chain is sometimes called the most important stage. First complete the sentence, then answer the question. The electron transport chain uses the transfer of protons between protein...
