RuBP, or ribulose bisphosphate, is a crucial molecule in photosynthesis.
Understanding RuBP
RuBP plays a vital role in the Calvin cycle, a light-independent process within photosynthesis. According to the reference, it is a 5-carbon molecule that is involved in the Calvin cycle, which is one of the photosynthesis's light-independent processes.
Key Function
- RuBP's main function is to bind with atmospheric carbon dioxide.
- This binding is facilitated by the enzyme RuBisCO.
- The combination of RuBP and carbon dioxide forms an unstable 6-carbon molecule. This molecule is then broken down into two 3-carbon molecules, starting the carbohydrate synthesis process.
