RuBisCO is an enzyme that acts both as a Carboxylase and oxygenase. Why do think RuBisCO carries out more Carboxylation in C4 plants?
Answers
Answer:
The increase in CO2 ensures that the enzyme RuBisCo does not act as an oxygenase, but as a carboxylase. This prevents photorespiration and increases the rate of photosynthesis. Thus, C4 plants are highly productive. ... Answer The enzyme RuBisCo is absent from the mesophyll cells of C4 plants.
Answer:
Explanation: In C4 plants,RUBISCO is present in the bundle sheath cells.
- The mesophyll cells of C4 plants have PEP carboxylase, to cause primary fixation of CO2 to form a 4C acid ( OAA) .
- the 4C acid is then , transported to the bundle sheath cells, undergoes decarboxylation to release CO2.
- This , the concentration of CO2 is high in the bundle sheath cells is high RUBISCO is operative to cause CO2 fixation through Calvin cycle.
- consequently, RUBISCO carries out more carboxylation in C4 plants.
