Question

1) Summarize how the electron transport chain functions to produce ATP in a bacterial cell versus a eukaryotic cell. Explain whether or not the term chemiosmosis accurately illustrates this process.

Answer 1

.In bacteria there are several different electron donors and several different electron acceptors. the donor may be NADH or succinate, in which case electrons enter the electron transport chain via NADH dehydrogenase (similar to Complex I in mitochondria) or succinate dehydrogenase. in eukaryotes, NADH is electron donor and electron acceptor is molecular oxygen.

.Chemiosmosis is the movement of ions across a selectively permeable membrane, down their electrochemical gradient. More specifically, it relates to the generation of ATP by the movement of hydrogen ions across a membrane during cellular respiration or photosynthesis. so chemiosmosis accurately illustrates this process
