Summary:To discover the possible mechanisms determining the level of energy metabolism during changes in the body size of animals, the content of mitochondrial protein was studied in planarians during starvation and feeding. In the course of starvation, the relative content of mitochondrial protein decreases, whereas during feeding it increases. Comparison of the experimental results with previous observations on respiration of planarians under similar conditions shows that changes in the level of respiration during starvation and feeding correlate with the content of mitochondrial protein. However, the degree of the functional load on the mitochondria must be taken into account under these circumstances.
