  2. Cellular respiration - Wikipedia

    en.wikipedia.org/wiki/Cellular_respiration

    Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from nutrients into ATP, and then release waste products. [1] Cellular respiration is a vital process that occurs in the cells of all [[plants and some bacteria ]].

  3. Propane - Wikipedia

    en.wikipedia.org/wiki/Propane

    Propane was first synthesized by the French chemist Marcellin Berthelot in 1857 during his researches on hydrogenation. Berthelot made propane by heating propylene dibromide (C 3 H 6 Br 2) with potassium iodide and water. [9] [10]: p. 9, §1.1 [11] Propane was found dissolved in Pennsylvanian light crude oil by Edmund Ronalds in 1864.

  4. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    In general outline, photosynthesis is the opposite of cellular respiration: while photosynthesis is a process of reduction of carbon dioxide to carbohydrates, cellular respiration is the oxidation of carbohydrates or other nutrients to carbon dioxide. Nutrients used in cellular respiration include carbohydrates, amino acids and fatty acids.

  5. Chemiosmosis - Wikipedia

    en.wikipedia.org/wiki/Chemiosmosis

    Directions of chemiosmotic proton transfer in the mitochondrion, chloroplast and in gram-negative bacterial cells (cellular respiration and photosynthesis). The bacterial cell wall is omitted, gram-positive bacterial cells do not have outer membrane. [6] The complete breakdown of glucose releasing its energy is called cellular respiration. The ...

  6. Cellular waste product - Wikipedia

    en.wikipedia.org/wiki/Cellular_waste_product

    Cellular waste products are formed as a by-product of cellular respiration, a series of processes and reactions that generate energy for the cell, in the form of ATP. One example of cellular respiration creating cellular waste products are aerobic respiration and anaerobic respiration .

  7. 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 ...

  8. Carbohydrate metabolism - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate_metabolism

    Plants synthesize carbohydrates from carbon dioxide and water through photosynthesis, allowing them to store energy absorbed from sunlight internally. [2] When animals and fungi consume plants, they use cellular respiration to break down these stored carbohydrates to make energy available to cells. [2]

  9. Respiration (physiology) - Wikipedia

    en.wikipedia.org/wiki/Respiration_(physiology)

    Although physiologic respiration is necessary to sustain cellular respiration and thus life in animals, the processes are distinct: cellular respiration takes place in individual cells of the organism, while physiologic respiration concerns the diffusion and transport of metabolites between the organism and the external environment.
