Final answer:
Electron-carrying prosthetic groups in the respiratory chain include hemes and iron-sulfur clusters, such as cytochrome c. Cytochrome c is a water-soluble protein with a heme group that carries electrons. Complex III and Complex I in the respiratory chain contain cytochrome c proteins with heme groups involved in electron transfer.
Step-by-step explanation:
The electron-carrying prosthetic groups that are attached to proteins in the respiratory chain include hemes and iron-sulfur cluster. Cytochrome c is an example of a protein with a heme group, which carries electrons and is water-soluble.
Complex III and Complex I both contain cytochrome c proteins with heme groups that are involved in electron transfer. Electron-carrying prosthetic groups in the respiratory chain include hemes and iron-sulfur clusters, such as cytochrome c. Cytochrome c is a water-soluble protein with a heme group that carries electrons.
