The scientist Charles Barnes first used the word 'photosynthesis' in 1893. This word is taken from two Greek words, photos, which means light, and synthesis, which in chemistry means making a substance by combining simpler substances. So, in the presence of light, synthesis of food is called 'photosynthesis'.
The average rate of energy captured by global photosynthesis is approximately 130 terawatts, [6] [7] [8] which is about eight times the total power consumption of human civilization. [9] Photosynthetic organisms also convert around 100–115 billion tons (91–104 Pg petagrams, or billions of metric tons), of carbon into biomass per year.
Plant cells with visible chloroplasts (from a moss, Plagiomnium affine) The Hill reaction is the light-driven transfer of electrons from water to Hill reagents (non-physiological oxidants) in a direction against the chemical potential gradient as part of photosynthesis.
6 H 2 O + 6 CO 2 + energy → C 6 H 12 O 6 + 6 O 2 where C 6 H 12 O 6 is glucose (which is subsequently transformed into other sugars , starches , cellulose , lignin , and so forth). The value of the photosynthetic efficiency is dependent on how light energy is defined – it depends on whether we count only the light that is absorbed, and on ...

2 O → glyceraldehyde-3-phosphate (G3P) + 6 NADP + + 9 ADP + 8 P i (P i = inorganic phosphate) Hexose (six-carbon) sugars are not products of the Calvin cycle. Although many texts list a product of photosynthesis as C 6 H 12 O 6, this is mainly for convenience to match the equation of aerobic respiration, where six-carbon sugars are oxidized ...
The judge overseeing the Arizona "fake elector" case against several of Donald Trump's allies has recused himself from the case after accusations of personal bias. Last week, defense attorneys for ...
