Abstract

In order to grow and divide, protozoa must assimilate building blocks for the synthesis of cell constituents (assimilatory metabolism). They also need free energy for the synthesis of macromolecules, for the maintenance of the integrity of the cell, and for various processes which enhance the survival of the cell (dissimilatory metabolism). Energy is also needed for osmotic and electric work and for motility. In heterotrophic eukaryotes, the assimilatory as well as the dissimilatory metabolism is based on organic molecules. In an ecological context it is of interest to know the efficiency of conversion of food to cell biomass and the rate at which this conversion takes place.
