The step of cellular respiration shown in the image is the electron transport chain. This is indicated by the involvement of NADH, the transfer of electrons through various enzymes (like Ubiquinone and Cytochrome reductase), the release of protons (\(H^+\)), and the final production of water from oxygen and electrons, ultimately leading to ATP synthesis through ATP synthase.
The illustration shows the mitochondrial intermembrane space. Molecules enter and exit enzymes. Molecule upper N upper A upper D upper H passes through enzyme upper N upper A upper D upper H Reductase releasing upper H superscript + baseline and upper N upper A upper D superscript + baseline. A blue arrow starts at upper N upper A upper D superscript + and goes through enzyme Ubiquinone then enzyme Cytochrome Reductase, an upper H superscript + baseline is released. The arrow continues through enzyme Cytochrome c and enzyme Cytochrome Oxydase, another upper H superscript + baseline is released. The formula 2 upper H + one-half upper O subscript 2 baseline is to the left of enzyme Cytochrome oxydase with an arrow pointing to the other side. The arrow meets with the arrow from upper N upper A upper D superscript + baseline at upper H subscript 2 baseline upper O. To the right is upper A upper T upper P synthase, upper A upper D upper P + upper P subscript 1 baseline have an arrow going under upper A upper T upper P synthase, an upper H superscript + baseline arrow points to the arrow, the result is upper A upper T upper P.

The step in cellular respiration that produces the most ATP is the electron transport chain. During this stage, the majority of ATP is generated through oxidative phosphorylation, utilizing the proton gradient created by the chain to drive ATP synthesis.

This is because corroboration by non-experts does not lend credibility to the data. Reliable sources typically have backing from experts in the relevant field. Typos, while not ideal, do not necessarily impact the reliability of the data itself, but the lack of expert corroboration indicates a potential issue with the source’s credibility.
