Table I. Total respiration and respiration in presence of mitochondrial inhibitors for the wild type, pgrl1, Δnd4, and Δnd4pgrl1

Total dark respiration (average ± sd, n > 3) expressed in nmol O2 × min−1 × 107 cells−1 ± sd and measured in the absence or in the presence of 100 μm rotenone, 1 mm KCN, or 1 mm SHAM for cells grown in CL 60 μE m−2 s−1.
