Oxgen, Fuel and a heat source
the plant is exposed to light
Two condition that must be present for light independent reactions to occur is the presence of CO2 and the presence of ribulose bisphosphate. Two other conditions include the presence of ATP and NADPH and the presence of required enzymes.
In order for respiration to occur, three things must be present: oxygen, a source of energy (such as glucose), and a metabolic system capable of breaking down the energy source to release energy for cellular processes.
