Plant cells glyoxylate cycle

The inhibitor would prevent the citric acid cycle from operating, but in germinating plant cells the glyoxylate cycle would be unaffected. Thus, energy production would be decreased in both cells, but their ability to synthesize glucose would be unimpaired. 

In plants, the synthesis of succinate from acetyl CoA in the glyoxylate cycle generates NADH. Glyoxysomes do not have an electron transport chain. Suggest a way in which NADH could be reoxidized in a plant cell so that the glyoxylate cycle can continue. 

Glyoxysome A specialized type of Peroxisome found in plant cells. It performs some of the reactions of photorespiration, and it also breaks down fatty acids to acetyl-CoA by P-oxidation and converts the acetyl-CoA to succinate via the glyoxylate cycle, thus enabling plants to convert fatty acids to carbohydrates.
