Abstract: 1. Metridium senile incorporated between 30% and 60% of the C14-labeled glysine, valine, glutamic acid, lysine, and an algal mixture when they were present at natural concentrations. 2. 33% of the glysine and 66% of the glutamic acid incorporated by the anemone was metabolized to CO2. This could account for 12% to 24% of the animal's total CO2 production. 3. The rates of release for glysine and glutamic acid are calculated. There is a net loss of glysine and a net uptake of glutamic acid by the anemone. 4. In starved versus fed anemones, the starved animals take up glysine and produce 14CO2 in significantly higher amounts. The advantage of this to Metridium senile is discussed.
