Abstract Einzelkontraktionen von Muskelfibrillen. Rhythmische Kontraktionen (Spermien und Trypanosomen) durch ATP und Pyrophosphat. Hemmung der Kontraktion durch SH-Reagenz; Entgiftung durch Cystein. Hemmung der Kontraktion durch Polysulfosäure und Reaktivierung durch Auswaschung. Streckbewegung von Zelle und Spindelapparat durch ATP (Phasenkontrastmikroskopische Aufnahmen).
Single contraction of muscle fibrils. Rhythmical contractions (sperms and trypanosomes) by ATP and diphosphate. Contraction inhibition by SH-reagents; detoxification by cysteine. Stretching movement of cell and spindle apparatus by ATP (phase-contrast microscopy).
