How does the presence of affect fixation in plants, and how do plants mitigate this effect?
competes with for RuBisCO in plants, reducing fixation. plants concentrate around RuBisCO in bundle sheath cells, minimizing this competition.
enhances fixation in plants. plants have no mechanism to regulate levels.
has no effect on fixation in plants. plants use PEP carboxylase to fix .
