Energy Metabolism

Abstract

Warburg (1908) was the first to describe a burst of oxygen consumption following fertilization of Arbacia eggs. This observation was followed by a number of investigations (see Giudice, 1973, and Yanagisawa, 1975 a, b for reviews), which confirmed this discovery. Recent studies have often employed the oxygen electrode (Nakazawa et al., 1970), which avoids errors due to CO2 displacement from sea water. The burst of oxygen consumption occurs within 1 min after fertilization, reaching, in two steps, values about 15 times higher than those of the unfertilized eggs. Oxygen consumption then decreases and reaches a plateau at a variable value generally a few times higher than that in the unfertilized egg (Fig. 3.1).
