Which two cellular organelles in eukaryotes have both electron transport systems and chemiosmotic mechanisms?
aalyn [17]

Answer:

Mitochondria and the chloroplast

Explanation:

Electron transport refers to the transfer of of electrons from electron donors to electron acceptors via a reduction-oxidation reaction.  

In the mitochondria the process is called Oxidative phosphorylation whereas in the Chloroplast it is called Photo-phosphorylation since it utilizes light.

Chemiosmotic mechanisms allow the movement of ions across a semi-permeable membrane down their electrochemical gradient.

In both mitochondria and chloroplast,have these mechanisms for the production of ATP .
