  2. Dietary fiber - Wikipedia

    en.wikipedia.org/wiki/Dietary_fiber

    Dietary fiber (fibre in Commonwealth English) or roughage is the portion of plant-derived food that cannot be completely broken down by human digestive enzymes. [1] Dietary fibers are diverse in chemical composition and can be grouped generally by their solubility , viscosity and fermentability which affect how fibers are processed in the body ...

  3. 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 .

  4. Carbohydrate metabolism - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate_metabolism

    When animals and fungi consume plants, they use cellular respiration to break down these stored carbohydrates to make energy available to cells. [2] Both animals and plants temporarily store the released energy in the form of high-energy molecules, such as adenosine triphosphate (ATP), for use in various cellular processes.

  5. Rumen - Wikipedia

    en.wikipedia.org/wiki/Rumen

    The rumen, also known as a paunch, is the largest stomach compartment in ruminants. [1] The rumen and the reticulum make up the reticulorumen in ruminant animals. [2]The diverse microbial communities in the rumen allows it to serve as the primary site for microbial fermentation of ingested feed, which is often fiber-rich roughage typically indigestible by mammalian digestive systems.

  6. Metabolic waste - Wikipedia

    en.wikipedia.org/wiki/Metabolic_waste

    Solid waste products may be manufactured as organic pigments derived from breakdown of pigments like hemoglobin, and inorganic salts like carbonates, bicarbonates, and phosphate, whether in ionic or in molecular form, are excreted as solids. [5] Animals dispose of solid waste as feces.

  7. Human nutrition - Wikipedia

    en.wikipedia.org/wiki/Human_nutrition

    Carbohydrates and proteins provide 17 kJ approximately (4 kcal) of energy per gram, while fats provide 37 kJ (9 kcal) per gram. [8] However, the net energy derived from the macronutrients depends on such factors as absorption and digestive effort, which vary substantially from instance to instance.

  8. Soybean meal - Wikipedia

    en.wikipedia.org/wiki/Soybean_meal

    Soybean meal is used in food and animal feeds, principally as a protein supplement, but also as a source of metabolizable energy. Typically 1 bushel (i.e. 60 lbs. or 27.2 kg) of soybeans yields 48 lbs. (21.8 kg) of soybean meal. [1] Most soybean meal is defatted, produced as a co-product of soybean oil extraction. [2]

  9. Cellular respiration - Wikipedia

    en.wikipedia.org/wiki/Cellular_respiration

    Cellular respiration is the process of oxidizing biological fuels using an inorganic electron acceptor, such as oxygen, to drive production of adenosine triphosphate (ATP), which contains energy. Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical ...
