3V-dependent increase of [ATPe] of <i>P. falciparum</i> infected RBCs.

<p>Values are expressed as ΔATP₁, i.e., the difference between [ATPe] at 1 min post-stimulus and basal [ATPe]. ΔATP₁ was plotted as a function of parasitemia (%) for r-RBCs (ring-infected erythrocytes; N = 8, n = 5), t-RBCs (trophozoite-infected erythrocytes; N = 19, n = 15) and s-RBCs (schizont-infected erythrocytes; N = 12, n = 15). N = independent preparations, n = replicates. The continuous lines represent positive parabolic functions fitted to experimental data. Spearman correlation coefficients were 0.6212, 0.8438 and 0.7946 to r, t and s-RBCs, respectively.
