In C4 plants, Rubisco is safeguarded from binding to oxygen through mechanisms such as being bound to PEP carboxylase. This binding mechanism helps maintain Rubisco's function and efficiency. The document discusses the protective strategies employed in the physiology of C4 plants.

1. In C4 plants, RuBisCO is protected from binding to Oxygen by... Multiple Choice being bound
to PEP carboxylase which protects RuBisCO. being molecularly altered so that it loses its
oxygenase function. being bound to PEP carboxylase which protects RuBisCO. being kept only
in bundle sheath cells.
