If plant gene alterations cause the plants to be deficient in photorespiration, what would most probably occur?
A) Photosynthetic efficiency would be reduced at low light intensities.
B) Cells would carry on the Calvin cycle at a much slower rate.
C) Less ATP would be generated.
D) There would be more light-induced damage to the cells.
E) Less oxygen would be produced.

Photorespiration maintains the redox balance with in a plant cell. In this process the RuBisCO enzyme takes in oxygen and oxygenates itself from RuBP to RuBisCO. It instead to fixing carbon causes loss of already-fixed carbon

It thus waste energy and reduce sugar synthesis thereby allowing usage of more light to photosynthesize so that the losses could be met. Else excess of photosynthesis and its product accumulation would disturb plant’s immunity and metabolism.

In this way photorespiration saves a plant cell from light induced damages.

Hence, option D is correct
