  "summary": "Mitochondrial complex I (CI) is a major entry point for NADH-derived electrons and an important site of redox regulation in most eukaryotes. However, apicomplexan parasites, including Toxoplasma gondii, lack CI, raising a fundamental question of how mitochondrial respiration is organized in these parasites. Here, we identify a parasite-specific mitochondrial microdomain that physically and…",
