Brief bio: I am currently a post-doc in Dr. Yair Shachar-Hill’s lab at Michigan State University working on metabolic flux analysis (MFA) focusing on central carbon metabolism in plant leaf. In the current work, I used 13C metabolic flux analysis to address the source of non-photorespiratory CO2 release, also known as respiration in the light (RL). This release has long been assumed to come from tricarboxylic acid cycle associated reactions, but this work determines that these fluxes are insufficient to explain measured non-photorespiratory CO2 release in the light. Furthermore, these findings add support to this release occurring from oxidative pentose phosphate pathway activity in the light.
