What Is Rubisco In Biology

Enolisation carboxylation hydration c c bond cleavage and protonation.

What is rubisco in biology. Nadph is the source of electrons for glucose biosynthesis. Rubisco and rubp sound. Rubisco shown here in a space filling model is the main enzyme responsible for carbon fixation in chloroplasts. Rubisco is involved in the first step of the calvin cycle helping carbon dioxide combine with a five carbon molecule called rubp or ribulose 1 5 bisphosphate.

Rubisco is one of many enzymes in the calvin cycle when rubisco facilitates the attack of co 2 at the c2 carbon of rubp and subsequent bond cleavage between the c3 and c2 carbon 2 molecules of glycerate 3 phosphate are formed. Rubisco joins three carbon dioxide molecules with three 5 carbon molecules that each have two phosphates. Free learning resources for students covering all major areas of biology.
