What Does Manganese Do In Photosynthesis

Manganese exerts its impact because of its role in the vital photosynthetic process which converts sunlight into plant energy ferrie explains.

What does manganese do in photosynthesis. Manganese is one of nine essential nutrients that plants require for growth. Besides these the manganese activates enzyme involved in photosynthesis and nitrogen metabolism. Manganese is also involved in pollen germination pollen tube growth root cell elongation and resistance to root pathogens. Manganese deficient cells were also more sensitive to cmu inhibition of photosynthesis.

Although the process of light energy conversion to chemical form by specialized plant cell organelles the chloroplasts is well understood many contemporary investigations have been concerned with the catalytic role played by manganese in oxygen evolution. Without magnesium chlorophyll cannot capture sun energy needed for photosynthesis. In short magnesium is required to give leaves their green color. Magnesium is the powerhouse behind photosynthesis in plants.

Adequate mn is critical in this system as mn facilitates the photolysis light splitting of water molecules and provides energy for photosynthesis. Treatment with 3 4 chlorophenyl 1 1 dimethylurea cmu also increased the rate of photoinhibition. Magnesium in plants is located in the enzymes in the heart of the chlorophyll molecule. New research has identified manganese as an unsung hero in the evolution of life on earth as it enabled a form of pre oxygen photosynthesis and helped protect against cellular oxidation.

Manganese dioxide is used as the cathode electron acceptor material in zinc carbon and alkaline batteries. Iron and molybdenum are biochemically involved in the nitrate reduction and nitrogen fixation. This role of manganese in plants is extremely crucial. All cultures showed first order kinetics for photoinhibition with the half time exponentially related to the mn concentration in the medium.

Many processes are dependent on this nutrient including chloroplast formation photosynthesis nitrogen metabolism and synthesis of some enzymes. In biology manganese ii ions function as cofactors for a large variety of enzymes with many functions. It affects chloroplast formation in leaves which. Function manganese is used in plants as a major contributor to various biological systems including photosynthesis respiration and nitrogen assimilation.
