Fig. 6. ATP levels upon treatment with an inhibitor to oxidative phosphorylation and an NO donor.

Fig. 6

ATP levels were assayed in syncytial embryos treated with cyanide (CN−), an irreversible inhibitor of oxidative phosphorylation, or the NO donor, SNAP. Fig. 6 is a plot of ATP levels (represented as the percentage of the normoxic, untreated control embryos) versus time of treatment. During 0.2% CN− treatment, ATP levels declined with an intermediate rate compared with exposure to <0.1 and 1.0% O2 (see Fig. 5B), decaying to 30% of untreated controls after 30 min. During treatment with 10 mm of SNAP, ATP levels remained high after 5 min (105% of untreated controls) and then began to decline after 15 min (86% of untreated controls).
