    Rubisco stands for

    A)  Ribulose bisphosphate carboxylase oxygenase

    B)  Ribulose phosphate carboxylase xygenase

    C)  Ribulose phosphate carboxylic oxygenase

    D)  None of the above

    Correct Answer: A

    Solution :

    Rubisco stands for ribulose bisphosphate carboxylase oxygenase. Ribulose 1,5-biphosphate (RuBP) is \[C{{O}_{2}}\] acceptor in \[{{C}_{3}}\]plants. RuBP combines with \[C{{O}_{2}}\] in presence of : (RuBP carboxylase) and form an -unstable 6-C compound. This compound this compound immediately broken into 2- molecules of, phophoglyceric acid (PGA) 3-phoshoglyceric acid is first stable compound formed in Calvin cycle. Rubisco enzyme (RuBP carboxylase) constitutes 16% of chloroplast protein. It is z most abundant protein on the earth.
