Question

Is photorespiration the opposite of photosynthesis?

Answer 1

Photosynthesis generates oxygen to replace that which is depleted by living organisms during respiration. One of the reactants required for photosynthesis is carbon dioxide, which is created during respiration. Both photosynthesis and cellular respiration are mutually beneficial processes.

Complete answer:
Yes, photorespiration is the process which is opposite of photosynthesis, in which carbon is oxidised within the plant cell.
In respiration, oxygen is used and carbon dioxide is released at all times of the day, whereas in photosynthesis, oxygen is used and carbon dioxide is released only when sunlight is present. Photosynthesis products are the reactants in respiration. As a result, spiration is thought to be the polar opposite of photosynthesis.

Photorespiration is the process of respiration in which carbon dioxide is exhaled rather than produced, which is the inverse of photosynthesis. Photophosphorylation occurs when ADP is phosphorylated to ATP with the help of energy from the sun.
The process of respiration is the reversal of photosynthesis. Sugars provide energy to animals such as ourselves. In cells, respiration takes place in the mitochondria. Sugar is broken down in a chemical interaction with oxygen during respiration.

Photorespiration utilises ATP and NADPH, the high-energy molecules produced by light reactions, according to biochemical studies. Photorespiration is thus a wasteful process since it stops plants from synthesising carbohydrates with their ATP and NADPH.

Photosynthesis occurs when the RuBisCO enzyme deals with carbon dioxide, whereas photorespiration happens when RuBisCO enzyme responds with oxygen. Furthermore, photorespiration reduces photosynthetic efficiency.
A new study suggests that photorespiration wastes little energy and instead enhances nitrate assimilation. The process that converts nitrate absorbed from the soil into protein. Photosynthesis is one of the most crucial life processes on Earth.

Note:-
Plants may not grow at a faster pace if photorespiration is reduced. Photorespiration may be required for nitrate absorption from soil. As a result, a reduction in photorespiration caused by genetic engineering or increased atmospheric carbon dioxide (due to fossil fuel combustion) may not be as beneficial to plants as previously thought. The link between photorespiration and nitrogen assimilation could be due to a number of physiological processes.
