Abstract:
Some quantitative data about the carbon-metabolism in Saccharomyces-cells of different ploidy were determined. The amount of carbon, necessary for the formation of a cell, proved to be proportional to the degree of ploidy of the cells. For the duplication of a diploid cell 6, 7·10-11 g glucose were used. In comparison with respiratory deficient cells the simultaneous utilization of fermentation and respiration metabolism in respiration sufficient cells leads to a decrease of the cell cycle duration, however, the energy needed for the formation of a cell is not decreased. The rate of cell multiplication has a maximum at assumptions about the utilization of the carbon marked glucose.
