It is a multi-party system whereby the executive power is exercised by the Prime Minister of the Council of Ministers as the head of government, as well as the President of Iraq, and legislative power is vested in the Council of Representatives and the Federation Council.
RuBP is ribulose biphosphate. It's purpose is in the dark reaction. It is formed by taking a phosphate, coming from the splitting of ATP, and joining it with RuP, changing RuP (ribulose phospate) into RuBP. RuBP is then able to join with CO2 and form an unstable 6C molecule which is the basis for the dark reaction.t's purpose is in the dark reaction.

  Ribulose bisphosphate, known as RuBP, is a 5-carbon sugar that is used in the Dark reactions (Calvin cycle) to fix carbon from CO2 (carbon dioxide). The Dark reactions b â¦ egin when one molecule of CO2 is attached to RuBP. This is where RuBisCO comes in.Ribulose-1,5-bisphosphate carboxylase/oxygenase is the enzyme that catalyzes the addition of the CO2 molecule to the RuBP. This forms an unstable 6-carbon compound which immediately splits to form two molecules of a 3-carbon compound called 3-phosphoglycerate (3-PGA) Hope that is helpful!ubisco is used from the very start of the Calvin Cycle. From the second that CO2 is taken in by the plant, Rubisco kick starts the process. Starting with phase 1: Carbon Fixation which is where phosphoglycerate, bisphosphoglycerate, ATP, as well as some NADPH are produced.
