  2. Calvin cycle - Wikipedia

    en.wikipedia.org/wiki/Calvin_cycle

    The Calvin cycle, light-independent reactions, bio synthetic phase, dark reactions, or photosynthetic carbon reduction (PCR) cycle[1] of photosynthesis is a series of chemical reactions that convert carbon dioxide and hydrogen-carrier compounds into glucose. The Calvin cycle is present in all photosynthetic eukaryotes and also many ...

  3. Glycolysis - Wikipedia

    en.wikipedia.org/wiki/Glycolysis

    Glycolysis is the metabolic pathway that converts glucose (C6H12O6) into pyruvate and, in most organisms, occurs in the liquid part of cells (the cytosol). The free energy released in this process is used to form the high-energy molecules adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide (NADH). [1]

  4. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    Photosynthesis (/ ˌfoʊtəˈsɪnθəsɪs / FOH-tə-SINTH-ə-sis) [ 1 ] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.

  5. Photosynthetic efficiency - Wikipedia

    en.wikipedia.org/wiki/Photosynthetic_efficiency

    The photosynthetic efficiency is the fraction of light energy converted into chemical energy during photosynthesis in green plants and algae. Photosynthesis can be described by the simplified chemical reaction. 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 ...

  6. Cellular respiration - Wikipedia

    en.wikipedia.org/wiki/Cellular_respiration

    The overall reaction can be expressed this way: [citation needed] Glucose + 2 NAD + + 2 P i + 2 ADP → 2 pyruvate + 2 NADH + 2 ATP + 2 H + + 2 H 2 O + energy. Starting with glucose, 1 ATP is used to donate a phosphate to glucose to produce glucose 6-phosphate. Glycogen can be converted into glucose 6-phosphate as well with the help of glycogen ...

  7. Carbohydrate metabolism - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate_metabolism

    Carbohydrate metabolism is the whole of the biochemical processes responsible for the metabolic formation, breakdown, and interconversion of carbohydrates in living organisms. Carbohydrates are central to many essential metabolic pathways. [1] Plants synthesize carbohydrates from carbon dioxide and water through photosynthesis, allowing them to ...

  8. Adenosine triphosphate - Wikipedia

    en.wikipedia.org/wiki/Adenosine_triphosphate

    Adenosine triphosphate (ATP) is a nucleoside triphosphate [2] that provides energy to drive and support many processes in living cells, such as muscle contraction, nerve impulse propagation, and chemical synthesis. Found in all known forms of life, it is often referred to as the "molecular unit of currency" for intracellular energy transfer. [3]

  9. Glucose - Wikipedia

    en.wikipedia.org/wiki/Glucose

    Glucose is a sugar with the molecular formula C 6 H 12 O 6. Glucose is overall the most abundant monosaccharide, [4] a subcategory of carbohydrates. Glucose is mainly made by plants and most algae during photosynthesis from water and carbon dioxide, using energy from sunlight.
