Proton production rate during glycolytic stress test.

Abstract

<p>The positive or notionally negative contribution of lactate from both anaerobic glycolysis (grey) and from CO₂/respiration (white) to the sum (black) proton production rate (PPR) are demonstrated for cardiomyocytes from each maturational time-point. The PPR is demonstrated in response to glucose (A) and oligomycin (B). Data shown are means ± SEM of 3–5 independent experiments. *p<0.05 by one way ANOVA and Tukey’s post-test.</p
