Final Answer:
RuBP carboxylase-oxidase (Rubisco) is an enzyme involved in the first step of photosynthesis, facilitating the carboxylation of ribulose-1,5-bisphosphate (RuBP).
Step-by-step explanation:
RuBP carboxylase-oxidase, commonly known as Rubisco, is a crucial enzyme in the process of photosynthesis. Its primary role is to catalyze the carboxylation of ribulose-1,5-bisphosphate (RuBP), a five-carbon compound, with carbon dioxide. This reaction initiates the Calvin cycle, a series of biochemical reactions responsible for the synthesis of organic molecules, such as glucose.
The enzyme plays a central role in carbon fixation, converting inorganic carbon (
) into organic molecules. Rubisco is considered one of the most abundant enzymes on Earth and is vital for the sustenance of life through the conversion of atmospheric carbon dioxide into essential organic compounds in plants and other photosynthetic organisms.
