The main biochemical function of the electron transport chain is to
Question 1 options:

use the energy of electrons to add phosphate groups to ATP to form ADP, with CO2 and water left over as waste.


use the energy of electrons to break glucose into pyruvic acid and convert NAD+ into NADH, forming many ATP in the cytosol during the process.


use the energy of electrons to move hydrogen protons across the inner mitochondrial membrane, so that a hydrogen ion gradient is formed within the intermembrane space.

use the power of electrons to force hydrogen ions through ATP synthase and into the intermembrane space, where water is the final product.
