  2. Photophosphorylation - Wikipedia

    en.wikipedia.org/wiki/Photophosphorylation

    This consumes the H + ions produced by the splitting of water, leading to a net production of 1/2O 2, ATP, and NADPH + H + with the consumption of solar photons and water. The concentration of NADPH in the chloroplast may help regulate which pathway electrons take through the light reactions.

  3. Calvin cycle - Wikipedia

    en.wikipedia.org/wiki/Calvin_cycle

    The enzyme phosphoglycerate kinase catalyses the phosphorylation of 3-PGA by ATP (which was produced in the light-dependent stage). 1,3-Bisphosphoglycerate (glycerate-1,3-bisphosphate) and ADP are the products. (However, note that two 3-PGAs are produced for every CO 2 that enters the cycle, so this step utilizes two ATP per CO 2 fixed ...

  4. Energy charge - Wikipedia

    en.wikipedia.org/wiki/Energy_charge

    Daniel Atkinson showed that when the energy charge increases from 0.6 to 1.0, the citrate lyase and phosphoribosyl pyrophosphate synthetase, two enzymes controlling anabolic (ATP-demanding) pathways are activated, [2] [3] while the phosphofructokinase and the pyruvate dehydrogenase, two enzymes controlling amphibolic pathways (supplying ATP as ...

    1 fadh 2 : 6 h + : 6/4 atp = 1 fadh 2 : 1.5 atp ATP : NADH+H + coming from glycolysis ratio during the oxidative phosphorylation is 1.5, as for FADH 2 , if hydrogen atoms (2H + +2e − ) are transferred from cytosolic NADH+H + to mitochondrial FAD by the glycerol phosphate shuttle located in the inner mitochondrial membrane.

  6. Photosynthetic efficiency - Wikipedia

    en.wikipedia.org/wiki/Photosynthetic_efficiency

    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 ...

  7. Phosphorylation - Wikipedia

    en.wikipedia.org/wiki/Phosphorylation

    Glycogen is a long-term store of glucose produced by the cells of the liver. In the liver , the synthesis of glycogen is directly correlated with blood glucose concentration. High blood glucose concentration causes an increase in intracellular levels of glucose 6-phosphate in the liver, skeletal muscle , and fat ( adipose ) tissue.

  8. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    Schematic of photosynthesis in plants. The carbohydrates produced are stored in or used by the plant. Composite image showing the global distribution of photosynthesis, including both oceanic phytoplankton and terrestrial vegetation. Dark red and blue-green indicate regions of high photosynthetic activity in the ocean and on land, respectively.

  9. Oxidative phosphorylation - Wikipedia

    en.wikipedia.org/wiki/Oxidative_phosphorylation

    1/2 O 2 + NADH + H + → H 2 O + NAD + The potential difference between these two redox pairs is 1.14 volt, which is equivalent to -52 kcal/mol or -2600 kJ per 6 mol of O 2. When one NADH is oxidized through the electron transfer chain, three ATPs are produced, which is equivalent to 7.3 kcal/mol x 3 = 21.9 kcal/mol. The conservation of the ...
