How is light energy converted into chemical energy during photosynthesis?

During photosynthesisCO2 consumption is necessary for the production of organic matter in the light. This reaction is accompanied by a release of O2. So theenergy solar is converted into chemical energy.

How to calculate photosynthetic efficiency?

Another parameter, thephotosynthetic efficiency” allows calculate this loss of energy. This is the ratio between the energy needed to produce one mole of oxygen (467 kJ) and the energy consumed. For example, the energy released by 8 moles of photons at a wavelength of 680 nm corresponds to 1760 kJ.

How do chlorophyllous plants convert light energy into chemical energy?

Photosynthesis allows chlorophyllous plants to absorb theenergy rays of the sun and convert it into chemical energy stored in the organic matter (glucose, starch) they produce from water, CO2 and mineral salts.

How is photosynthesis formed?

It is formed from the phosphorylation of ADP (adenosine diphosphate), by ATP synthase, an enzyme present on the thylakoid membrane. ATP and RH 2 are used during the second phase of photosynthesis, the chemical phase.

How much energy do plants use during photosynthesis?

The part of the solar spectrum used by plants has an estimated average wavelength of 570 nm; therefore, the light energy used during photosynthesis is about 28,600/570, or 50 kcal per einstein. [4] Even under the canopy, light is not really a limiting factor.

What is the difference between light quality and photosynthesis?

For photosynthesis, the quality of light matters more than the quantity. A molecule like chlorophyll a (the most abundant form of chlorophyll) effectively absorbs light in the violet, red, orange and a little in the yellow. Chlorophyll b is most effective in the blue region of the spectrum.

What is the impact of light on photosynthesis?

[5] Robert Emerson (), American biologist, author of numerous and major works for understanding the impact of light on photosynthesis (quantum yield, “Emerson” effect, etc.). His work is the first experimental demonstration of the existence of two photosystems in chloroplasts.
