Several properties of carbon dioxide in the blood affect its transport. First, carbon dioxide is more soluble in blood than oxygen. About 5 to 7 percent of all carbon dioxide is dissolved in the plasma. Second, carbon dioxide can bind to plasma proteins or can enter red blood cells and bind to hemoglobin.

Photorespiration in C3 and C4 Plants – Explanation and ...

Photorespiration in C3 Plants. Any O2 binds to RuBisCO in C3 plants and hence CO2 fixation is reduced. Here the RuBP binds with O2 instead of being converted into 2 PGA molecules to form one phosphoglycerate and phosphoglycolate molecule in a pathway called photorespiration. There is no synthesis of sugars or ATP in the photorespiratory pathway.

Reactive oxygen species (ROS) are produced as a normal product of plant cellular metabolism. Various environmental stresses lead to excessive production of ROS causing progressive oxidative damage and ultimately cell death.

Plants can absorb nitrogen either as nitrate (NO3) or ammonium (NH4+), and so the total uptake of nitrogen usually consists of a combination of these two forms. It's no surprise, then, that the ratio between these two forms of nitrogen is highly significance, and affects both the plants and the medium.

 · If plants did not do this, the presence of plants would not have substantially increased the O2 content of the atmosphere today relative to values prior to the carboniferous. Ergo, it is simply wrong to assume that any excess draw down of CO2 due to the CO2 fertilization effect will not only be matched, but exceeded by an increased production of CO2 by cellular respiration.

The explanation to Warburg effect lies in the phenomenon of photorespiration. In C 3 plants the rate of light respiration is faster than the dark respiration. This enhanced rate of respiration is called as photorespiration. It operates in high light intensity, high oxygen concentration and high temperature.
