SYNOPSIS. Most tricarboxylic acid cycle intermediates are oxidized by intact cells of the apochlorotic flagellate Astasia longa (Jahn). Use of these substrates depends on the pH of the medium. The acetate‐stimulated respiration is much more sensitive to metabolic inhibitors than is cell motility. The following glyoxylate cycle and/or tricarboxylic acid cycle enzymes have been demonstrated in cell‐free extracts: acetic‐thiokinase, condensing‐enzyme, aconitase, TPN‐isocitric dehydrogenase, succinic dehydrogenase, fumarase, and malic dehydrogenase.
