Respiration that is initiated in chloroplasts and occurs in light only is called photorespiration. Photorespiration or Glycolate Pathway: It is interesting to know that in the plants possessing Calvin cycle, the enzyme RuBP carboxylase can initiate the reversal of photosynthetic reactions. This process occurs when there is low CO2, concentration but high O2, concentration. At mid-day, when temperature and CO2 [...]
The upcoming discussion will update you about the difference between c3 plants and c4 plants. Difference # C3 Plants: 1. CO2 acceptor is RuBP (Ribulose bisphosphate). 2. Only one type of chloroplasts occur in the cells. Grana present in chloroplasts. 3. First stable compound after CO2 fixation is PGA. 4. Plants photosynthesize well, if CO2 concentration is high. 5. They [...]
The upcoming discussion will update you about the difference between Photorespiration and True Respiration. 1. Effect of O2 Concentration: The most obvious difference between true respiration and photorespiration is the effect of oxygen concentration on the rate of two processes. In most tissues true respiration is saturated at oxygen concentration of 2-3% and and beyond this percentage virtually no increase [...]
