Photorespiration (also known as the oxidative photosynthetic carbon cycle, or C2 photosynthesis) refers to a process in plant metabolism where the enzyme RuBisCO oxygenates RuBP, causing some of the energy produced by photosynthesis to be wasted. The desired reaction is the addition of carbon dioxide to RuBP (carboxylation), a key step in the Calvin–Benson cycle, however approximately 25% of reactions by RuBisCO instead add oxygen to RuBP (oxygenation), creating a product that cannot be used within the Calvin–Benson cycle. This process reduces the efficiency of photosynthesis, potentially reducing photosynthetic output by 25% in C3 plants.[1]
Photorespiration Tutor is an app designed to help you learn the chemical reactions involved in photorespiration, also known as the oxidative photosynthetic carbon cycle or C2 photosynthesis. Photorespiration involves a complex network of enzyme reactions that exchange metabolites between chloroplasts, leaf peroxisomes and mitochondria. You will learn the names and structures of each reactant, each product, each coreactant, and each byproduct. You will learn the names of each enzyme responsible for each reaction and in which organelle those enzymes are located. You will learn also in which organelle each metabolite translocation enzyme resides. Excellent study aid for your plant physiology and botany courses.
