Rubisco is considered to be the most important enzyme on Earth because it plays a crucial role in the process of photosynthesis, which is essential for the production of oxygen and organic molecules that sustain life on our planet. Rubisco is responsible for catalyzing the first step in the Calvin cycle, where carbon dioxide from the atmosphere is converted into glucose and other organic compounds that serve as the basis for the food chain. Without rubisco, this process would not be possible, and life as we know it would not be able to exist.
