[Research progress on energy metabolism of Plasmodium at erythrocytic stage]

As a single-cell organism, Plasmodium has a large and complex metabolic network system. There is a close relationship between various metabolic pathways to maintain the transformation of Plasmodium's own energy and substances. Plasmodium energy metabolism pathways mainly include glycolysis and oxidative phosphorylation. Among them, Plasmodium at the erythrocytic stage takes glycolysis as the main energy supply method, and less energy is generated by oxidative phosphorylation. In addition, the two carbon metabolism pathways closely relating to energy metabolism are the tricarboxylic acid(TCA) cycle pathway and glutamate metabolism pathway. As the core of metabolism, the TCA cycle connects glycolysis and glutamate metabolism; glutamate metabolism, as the main carbon metabolism pathway, also participates in various metabolic pathways, such as pyrimidine metabolism, porphyrin metabolism, and protein biosynthesis. This article reviews the energy metabolism pathways of Plasmodium and carbon metabolism pathways that are closely related to energy metabolism, in order to deepen the understanding of the energy metabolism of Plasmodium at the erythrocytic stage, and then provide the theoretical basis and references for studying the mechanisms of action and the drug resistance of antimalarial drugs.
