Question

Is the sum of the redox reactions of the electron transport chain strongly or weakly exergonic? Why is that?

Answer 1

Electron transport

A redox reaction is simply used for an oxidation-reduction reaction. some molecules in chemical reaction will be oxidized and some will be reduced.

A molecule that is oxidized loses electrons, and a molecule that is reduced gains electrons.

There's a lot of energy stored in the bonds between the atoms in the molecules.

Redox reactions basically transfer this bond energy in the form of electrons called electron carriers.

By using electron carriers, the harvested energy is used to convert the energy into final product.

Therefore, An electrochemical gradient will be established using the energy released by exergonic redox reactions.

-The electrons will release a small amount of energy with each redox step.

the sum of the redox reactions of the electron transport chain is strongly exergonic.
