A newly discovered unicellular eukaryote contains an organelle that produces ATP. The organelle is surrounded by two membranes; the inner membrane contains proteins similar to bacterial electron transport proteins. The organelle also contains circular DNA and ribosomes that are smaller than cytosolic ribosomes. When treated with an antibiotic that inhibits bacterial ribosomes, synthesis of several organelle-encoded proteins decreases while cytosolic protein synthesis is unaffected. Which evidence best supports an endosymbiotic origin for this organelle?
