Effects of SWCNTs on mitochondrial bioenergetics. A Seahorse assay was used to determine the oxygen consumption rate of SAEC exposed to different doses of SWCNTs for 24 hours. Overall oxygen consumption rate (A), basal respiration (B), ATP-linked respiration (C), maximal respiration (D), spare capacity (E), proton leak (F), and non-mitochondrial respiration (G) were measured and calculated. A total of six replicates per group were measured and data presented as Mean ± SD.
