TCA cycle (plant) (WP3009)

Oryza sativa

The TCA cycle mediates the catabolism of acetyl-CoA to yield two molecules of CO2 and reducing equivalents in the form of NADH + H+ and FADH2. In plants, it is also an important source of carbon skeletons for biosynthetic reactions. Description from [http://plantreactome.gramene.org/ Plant Reactome]. Developed by Gramene.org.
