As it gets hotter, Rubisco becomes even more prone to errors.

This carbon-fixation reaction is carried out by the enzyme Rubisco as part of the Calvin- Benson cycle.

Because of this very important role in photosynthesis, Rubisco is probably the most abundant enzyme on earth.

Meanwhile, the Rubisco in C4 plants already gets enough CO₂ and
so increases should have little effect on them.

Rubisco catalyzes a reaction between CO 2 and RuBP,
which forms a six-carbon compound that is immediately converted into two three-carbon compounds.

Unfortunately, stopping water getting out
of their leaves also stops CO₂ getting in and, as Rubisco becomes starved of CO₂,
it wastes more and more of the plant's resources by using oxygen instead.
