Photosynthesis process

What is the source of the vast amount of energy consumed by our mechanized society The largest of all of our energy sources is the sun, and energy from the sun is stored in our fuels (wood, coal, petroleum) as a result of the photosynthesis process. 

On this planet, of what value would be an eye that is sensitive only to light in the ultraviolet spectral region Discuss the evolutionary significance of the facts that the human eye and the photosynthesis process are both dependent upon light in the part of the spectrum called the visible. ... 

The outcome of the photosynthesis processes is ultimately similar in all green plants carbon dioxide from the atmosphere is taken up by the plants, where it reacts with water to form carbohydrates and oxygen the carbohydrates are assimilated by the plants while the oxygen is released to the atmosphere (see Textbox 53). Extensive studies have shown that the conversion of carbon dioxide and water into carbohydrates in different plants may follow, however, one of three different photosynthetic pathways, which are usually referred to as the C3, C4, and CAM paths. Each type of plant follows just one of these three pathways. 

C3 plants Plants as, for example, cotton and wheat, in which, during the photosynthesis process, a stable compound consisting of three bonded carbon atoms is first formed during the fixation of carbon derived from carbon dioxide in the plants over 95% of the plant species on the earth are C3 plants see C4 and CAM plants. 

Photosynthesis - process of converting electromagnetic energy of the sun rays into the energy of chemical bonds of vital organic substances. .. [1]. 

The amide functionality plays an important role in the physical and chemical properties of proteins and peptides, especially in their ability to be involved in the photoinduced electron transfer process. Polyamides and proteins are known to take part in the biological electron transport mechanism for oxidation-reduction and photosynthesis processes. Therefore studies of the photochemistry of proteins or peptides are very important. Irradiation (at 254 nm) of the simplest dipeptide, glycylglycine, in aqueous solution affords carbon dioxide, ammonia and acetamide in relatively high yields and quantum yield (0.44)202 (equation 147). The reaction mechanism is thought to involve an electron transfer process. The isolation of intermediates such as IV-hydroxymethylacetamide and 7V-glycylglycyl-methyl acetamide confirmed the electron-transfer initiated free radical processes203 (equation 148).

The naphthalimide hydroperoxides 44 and 45 are called artificial photonucleases for their in vitro ability of intercalating in the DNA structure and causing photochemically induced cleavage . Lipid hydroperoxides interfere with the photosynthesis process.

Phytoplankton production RpA in environment A is a function of solar radiation Ea, concentration of nutrients nA, temperature TA, phytoplankton biomass pA, and concentration of pollutants A. There are many models that describe the photosynthesis process (Legendre and Legendre, 1998 Legendre and Krapivin, 1992). For the description of this function in the present study, an equation of Michaelis-Menten type is used (block MFB) ... 

The approach for this system is the mimicry of the highly efficient photosynthesis process in biological systems, by which an antenna device collects the light energy before a series of exciton, energy, and electron transfers, which lead to the synthesis of the plant s fuel.70-73...
