Carboxylase in A Sentence

    1

    The outer layer (the mesophyll) fixes CO2 using the enzyme PEP carboxylase to form 4-carbon organic acids.

    2

    This carbon-fixing reaction is catalyzed by the enzyme ribulose bisphosphate carboxylase, always known as rubisco.

    3

    This in itself was not surprising, since plants normally fix CO2 in the dark using PEP carboxylase as part of their respiratory pathway.
