Explanation:

The electron - transport chain is part of cellular respiration. The enzyme - containing complexes of the electron - transport chain are located on the cristae of the mitochondrion, which are the folded inner membranes of the mitochondria. The outer membrane of the mitochondrion does not house these complexes. The cytosol is the fluid part of the cytoplasm and is not the location for the electron - transport chain complexes. The nucleus is the control center of the cell and has no relation to the location of the electron - transport chain complexes.

Answer:

cristae of the mitochondrion
