What is the role of the enzymes (i) rubisco and (ii) PEPCo and where are they present?
Answers
Answer:
The enzyme Rubisco, short for ribulose-1,5-bisphosphate carboxylase/oxygenase, is the enzyme that incorporates CO2 into plants during photosynthesis. As it constitutes about 30% of the total protein in a plant leaf, Rubisco is probably the most abundant protein on earth and a major sink for plant nitrogen.
Answer:
RUBISCO or Ribulose bis phosphate carboxylase helps in carbondioxide fixation during dark reaction .PEPco or phosphoenolcarboxy kinase helps in the formation of oxaloacetate from phosphoenolpyruvate .
Explanation:
Role of RUBISCO
Ribulosebis phosphate carboxylase helps in the conversion of ribulose bis phosphate to phosphoglyceric acid in presence of carbon di oxide.This step is initiates the dark reaction of photosynthesis
Role of PEPco
phosphoenolpyruvate carboxylase helps in the formation of oxaloacetate from phosphoenol pyruvate by utilizing carbon di oxide in bicacarbonate form.This reaction initiate the C4 cycle.
