Abstract
1. 1. Radioactive asparagine has been isolated from lupine seedlings, which were permitted to carry on photosynthesis for 6 days in the presence of C 14O 2. It was found to contain 55% of its activity in the α-carboxyl. 2. 2. Radioactive asparagine was vacuum infiltrated into wheat and lupine seedlings, and its subsequent metabolism was observed. 3. 3. Utilization of asparagine for both CO 2 production and the synthesis of cells was observed in all cases. This was true even in young lupine seedlings before they develop their photosynthetic mechanism. 4. 4. Radioactive glucose, infiltrated into lupine seedlings, was utilized 2 1 2 –5 times faster than asparagine. Although glucose was used about equally for respiration and cell synthesis, asparagine was used mainly for the synthesis of cells.
