The simple carbon sugars photosynthesis produces are then used to form other organic compounds, such as the building material cellulose, the precursors for lipid and amino acid biosynthesis, or as a fuel in cellular respiration. The latter occurs not only in plants but also in animals when the carbon and energy from plants is passed through a ...
In anoxygenic photosynthesis, various electron donors are used. Cytochrome b 6 f and ATP synthase work together to produce ATP (photophosphorylation) in two distinct ways. In non-cyclic photophosphorylation, cytochrome b 6 f uses electrons from PSII and energy from PSI [citation needed] to pump protons from the stroma to the lumen. The ...
Photoautotrophs are organisms that can utilize light energy from sunlight and elements (such as carbon) from inorganic compounds to produce organic materials needed to sustain their own metabolism (i.e. autotrophy). Such biological activities are known as photosynthesis, and examples of such organisms include plants, algae and cyanobacteria.
Photosynthesis is the main means by which plants, algae and many bacteria produce organic compounds and oxygen from carbon dioxide and water (green arrow). An autotroph is an organism that can convert abiotic sources of energy into energy stored in organic compounds , which can be used by other organisms .
[citation needed] The sum of reactions in the Calvin cycle is the following: [citation needed] 3 CO 2 + 6 NADPH + 9 ATP + 5 H 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 ...
The following is a breakdown of the energetics of the photosynthesis process from Photosynthesis by Hall and Rao: [6]. Starting with the solar spectrum falling on a leaf, 47% lost due to photons outside the 400–700 nm active range (chlorophyll uses photons between 400 and 700 nm, extracting the energy of one 700 nm photon from each one)
The cost of raw materials needed to make electric vehicles is rising. The average cost in raw materials is now around $8,255 per vehicle, according to consulting firm AlixPartners.
Pictured from top to bottom, (A) benzophenone, (B) methylene blue, and (C) rose Bengal are all organic photosensitizers. All metals involved are purely counterions to keep the material in the solid state as a salt. Organometallic photosensitizers contain a metal atom chelated to at least one organic ligand. The photosensitizing capacities of ...
