State III respiration was markedly temperature-dependent in mitochondria from control flies with both substrates; it was maximal at 24\u201329 \u02daC and fell progressively at higher measuring temperatures. In mitochondria from thermotolerant flies, state III respiration was less temperature-dependent with both substrates but this was most marked for G3P. The effect of experimental temperature on state IV respiration was similar in mitochondria from control and thermotolerant flies with each substrate, but differed between the two substrates. With G3P as substrate, respiration rate rose with temperature with a Q10 of approximately 1.5; however, with P+P as substrate, the trend was for respiration rate to fall as experimental temperature rose.<\/jats:p>\n               <jats:p>Using G3P as substrate, acceptor control was demonstrable at 34 \u02daC in some preparations of mitochondria from thermotolerant flies but not in those from control flies at that temperature.
