Rubiso is an enzyme that can catelyze two entirely different process during day time in plants.

a)*What are these reactions?

b)*What is the full form of RuBISO?

c)*In one reaction chl- is evolced, what cell organans are are involved in other reaction?

1. RuBp( Ribulose-1,5-bisphosphate) is an organic substance that is involved in photosynthesis. The enzyme RuBp is the most important and abundant enzyme in the plant world. RuBp initiates carboxylation of ribulose-1,5,biphosphate to produce a transient 6- carbon  compound called 2-carboxy 3-keto 1, 5- biphosphoribitol which splits into 2 molecules of 3-PGA.

• Under some specific conditions like high oxygen concentration and light, it catalyzes oxygen with ribulose biphosphate. This reaction is called oxygenation which leads to the formation of one molecule of 2- phosphoglycolic acid and one molecule of 3- phosphoglyceric acid. The oxygenation leads to the photorespiration process.

  b. Ribulose-1,5-Bisphosphate Carboxylase Oxygenase, commonly known by the abbreviation RuBisCO.
