    Course on Plant Metabolisme and Metabolites
    (Echahid Cheikh Larbi Tebessi University- Tebessa, 2026) Mehalaine Souad
    Plant metabolism is an essential subject for students to build deep information about plant ability of synthesis a large amount of compounds used in its physiology, structure, and adaptation. In this context, this scientific document contains courses of the scientific subject: Plant Metabolism and Metabolites intended for Master I students in Plant Ecophysiology. The document contains five chapters. The first chapter concerns the concept and importance of primary and secondary metabolism with which the plant establishes relationships with other living beings in its environment. The second chapter explains the notion of catalysis and enzymatic regulation in plants. The third chapter details the main metabolic pathways and the important classes of secondary metabolites, namely phenolic compounds, terpenoids, and alkaloids. The fourth chapter illustrates the contribution of molecular biology and genetics to understanding the conditions leading to the expression of enzyme genes involved in the process of adaptation and defense to different environmental constraints through the study of some metabolic pathways. The last chapter is devoted to the study of biological membranes, notably the plasma membrane and their role in the response to stimuli through the intervention of regulatory enzymes; example the enzymes of phenolic metabolism.
