- Option 4)
respiration
Answers (1)
As learnt in
Photorespiration -
A process in plant metabolism where enzyme RuBisCO oxygenates RuBP, causing some of the energy produced by photosynthesis to be wasted.
- wherein
O2 enters Calvin cycle instead of Co2 this results in reduced rate of photosynthesis.
Calvin cycle -
Involves CO2 fixation in the presence of ATP and NADPH and its conversion to glucose, through a series of reactions
Net Reaction:
- wherein
Discovered by Calvin and Benson. Divided into three phases:
1) Carborylation
2) Glycolytic reversal
3) Regeneration of RuBP
Hatch Slack pathway -
Regular mode of CO2 fixation in number of tropical plants. First product is 4-carbon compound, hence, known as C4.
- wherein
Photorespiration is present in C3 but almost absent in C4 plants.
