Course Topics
• Structure and functions of biological macromolecules: amino acids and proteins, carbohydrates and lipids (including case studies on phytosiderophores, intercropping strategies for Fe acquisition, protein folding, glutathione roles in photoprotection, phytochelatins and heavy metal detoxification).
• The enzyme kinetics, inhibition, regulation of membrane and soluble enzyme systems; isoenzymes (including feedback regulation (EPSP synthase/glyphosate), allosteric regulation, environmental modulation of enzyme activity, and case studies such as root nitrate uptake and PM-ATPase modulation).
• Bioenergetics: energy changes in biological systems, forecasting feasibility of reactions, exo- and endo-endergonic reactions and calculation of DeltaG and DeltaG0, and mechanisms of energy transfer.
• Composition and functions of cell membranes: energy of trans-membrane transport, structure and function of membrane proteins, transport of ions and metabolites. (including solute transport (diffusion, active transport) and long-distance transport in xylem and phloem; resilience strategies such as callose deposition in grapevine) Root uptake of Nutrients, their transolcation and allocation at the leaf and fruit level.
• Oxidative metabolisms: glycolysis and its regulation; tricarboxylic acid cycle and its regulation, the mitochondrial electron transport chain, oxidative phosphorylation, cyanide-resistant respiration, Beta-oxidation of fatty acids and glyoxylate cycle, the cycle of the pentose phosphate.
• Photosynthesis: Pigments and their synthesis, light absorption and energy transfer, photosystems and bright reactions, photophosphorilation, incorporation and reduction of CO2, C3, C4 and CAM plants, photorespiration and glycolate metabolism (including TLC analysis of pigments and strategies to control the respiratory process in agricultural products).
• Absorption and assimilation of nitrogen and sulfur compounds: mechanisms of trans-membrane transport, nitrate reduction, the GS-GOGAT system, sulfate reduction and assimilation.
• Plant mineral nutrition: the biochemical role of macro- and micronutrients
Laboratory activities
• Preparation of hydroponic solutions and plant growth experiments.
• Amino acid titration, size-exclusion chromatography, dialysis.
• Isolation and purification of plasma membrane H+-ATPase. Spectrophotometry and protein quantification.
• Production of biodiesel and soap from plant oils. Synthesis of starch-based bioplastics. Thin-layer chromatography (TLC) of leaf pigments.
• In vitro and in vivo enzymatic assays (including FeIII-chelate reductase activity).
Each activity is paired with self-assessment quizzes on the Teams platform.

Teaching format
The course consists of lectures during which the Professor presents the different topics. Practical lessons and laboratory activities conducted by the Teacher and the Teaching Assistants are also foreseen. Course topics will be presented using Power Point presentations and at the end of a single lesson a pdf copy will be distributed directly to students.
Interactive learning methods include student-led presentations revisiting and summarizing the most important concepts of the last lecture, followed by Q&A sessions, group-based/cooperative exercises, online self-assessment quizzes, and open discussions for feedback on teaching and learning approaches.
