The step of cellular respiration shown in the image is the electron transport chain. The processes described involve the transfer of electrons through various enzyme complexes (NADH Reductase, Ubiquinone, Cytochrome Reductase, Cytochrome c, and Cytochrome Oxidase) and the production of water and ATP, which are characteristic of the electron transport chain.
Use the image below to answer the question.
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.
