Fig. 5From: Using a chimeric respiratory chain and EPR spectroscopy to determine the origin of semiquinone species previously assigned to mitochondrial complex IThe effect of carboxin on complex II semiquinone signals at 12 K. AOX-SMPs were prepared and measured as in Fig. 4 but at 12 K. Vertical lines indicate g values for the SQ-SQ radical pair of complex II as previously reported [34]Back to article page
