RubiscoAktivität
Rubisco Aktivität refers to the catalytic rate of the enzyme Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco). Rubisco is a crucial enzyme in photosynthesis, catalyzing the initial step of carbon fixation by converting atmospheric carbon dioxide into organic compounds. Its activity is a key determinant of photosynthetic efficiency in plants and other photosynthetic organisms. The term encompasses both the carboxylation reaction, which leads to sugar production, and the oxygenation reaction, which initiates photorespiration and reduces photosynthetic output. Factors such as temperature, pH, substrate concentrations (CO2 and RuBP), and the presence of activase proteins significantly influence Rubisco Aktivität. Understanding and optimizing Rubisco Aktivität is a major focus in plant biology and agricultural research, aiming to enhance crop yields and carbon sequestration.
