Question

In the maize plant, \[\ce{CO2}\] fixation occurs in both mesophyll and bundle sheath cells. The enzymes involved in these cells for the process respectively are, ______. 

पर्याय

• RuBisCO and PEP Kinase

• PEP Kinase and Pepsin

• RuBisCO and PEP Carboxylase

• PEP Carboxylase and RuBisCO

Answer 1

In the maize plant, \[\ce{CO2}\] fixation occurs in both mesophyll and bundle sheath cells. The enzymes involved in these cells for the process respectively are PEP Carboxylase and RuBisCO. 

Explanation:

In \[\ce{C4}\] plants (such as maize), \[\ce{CO2}\]  fixation takes place twice. PEP carboxylase firstly in mesophyll cells, and RuBisCO secondly in bundle sheath cells.
