Effect of salt.

Abstract

<p>Initial velocities at 5°C are plotted <i>vs.</i> substrate concentration. <b>A.</b> Titration of BQ at [NADH] = 100 µM with no salt (circles), 0.25 M NaCl (squares), and 0.5 M NaCl (triangles). <b>B.</b> Titration of DCPIP at [NADH] = 100 µM; symbols as in panel A. Solid lines are intended only to guide the eye and do not represent fits to the data.</p
