The metabolism of glycine and glycollate by pea leaves in relation to photosynthesis
1.
1. The metabolism of 14C-labelled glycollate and glycine both to sucrose and to a polyglucan via serine has been demonstrated in excised pea leaves. The effect of light, DCMU, isonicotinyl hydrazide and the partial pressure of CO2 on the pathway has been studied.
2.
2. The metabolism of [14C]glycine and serine formed during a preceding period of photosynthesis has been followed during a subsequent period of photosynthesis in 12CO2. The radioactivity in the glycine and serine declined whilst that in sucrose rose, suggesting that in photosynthesis some sucrose is formed via glycine and serine. The effect of changes in partial pressure of carbon dioxide indicates that the photosynthetic pathway may be spatially separated from that which metabolises exogenous glycine and glycollate.
