Question

The C4 pathway (Hatch-Slack) uses which enzyme for the initial CO2 fixation?

Accepted Answer

C. PEP carboxylase (in mesophyll cells)

In C4, PEP carboxylase in MESOPHYLL cells fixes CO2 into oxaloacetate (4C).
Transported to BUNDLE SHEATH cells where RuBisCO then does the Calvin cycle.
PEP carboxylase has higher affinity for CO2; less photorespiration.

Answer

RuBisCO (in mesophyll cells)

Answer

RuBisCO (in bundle-sheath cells)
