Question

What is RuBP? Where is it found in a C${}_3$ plant? What is its role in biosynthesis process?

Answer 1

RuBP stands for ribulose bisphosphate and is a 5 carbon compound involved in the Calvin cycle, which is part of the light independent reactions of photosynthesis. Atmospheric carbon dioxide is combined with RuBP to form a 6 carbon compound, with the help of an enzyme called RuBisCO. It is found in the mesophyll cells. It enables plants to 'fix' carbon from the atmosphere and convert into photosynthetic products.
