  2. Fatty acid metabolism - Wikipedia

    en.wikipedia.org/wiki/Fatty_acid_metabolism

    In catabolism, fatty acids are metabolized to produce energy, mainly in the form of adenosine triphosphate (ATP). When compared to other macronutrient classes (carbohydrates and protein), fatty acids yield the most ATP on an energy per gram basis, when they are completely oxidized to CO 2 and water by beta oxidation and the citric acid cycle.

  3. Lipogenesis - Wikipedia

    en.wikipedia.org/wiki/Lipogenesis

    AMP and ATP concentrations of the cell act as a measure of the ATP needs of a cell. When ATP is depleted, there is a rise in 5'AMP. This rise activates AMP-activated protein kinase, which phosphorylates ACC and thereby inhibits fat synthesis. This is a useful way to ensure that glucose is not diverted down a storage pathway in times when energy ...

  4. Composition of the human body - Wikipedia

    en.wikipedia.org/wiki/Composition_of_the_human_body

    The average 70 kg (150 lb) adult human body contains approximately 7 × 10 27 atoms and contains at least detectable traces of 60 chemical elements. [5] About 29 of these elements are thought to play an active positive role in life and health in humans. [6]

  5. Adenosine triphosphate - Wikipedia

    en.wikipedia.org/wiki/Adenosine_triphosphate

    The energy used by human cells in an adult requires the hydrolysis of 100 to 150 mol/L of ATP daily, which means a human will typically use their body weight worth of ATP over the course of the day. [30] Each equivalent of ATP is recycled 1000–1500 times during a single day (150 / 0.1 = 1500), [29] at approximately 9×10 20 molecules/s. [29]

  6. Bioenergetic systems - Wikipedia

    en.wikipedia.org/wiki/Bioenergetic_systems

    ATP–CP system (phosphagen system) – At maximum intensity, this system is used for up to 10–15 seconds. [5] The ATP–CP system neither uses oxygen nor produces lactic acid if oxygen is unavailable and is thus called alactic anaerobic. This is the primary system behind very short, powerful movements like a golf swing, a 100 m sprint or ...

  8. Lipid metabolism - Wikipedia

    en.wikipedia.org/wiki/Lipid_metabolism

    Lipid metabolism is often considered the digestion and absorption process of dietary fat; however, there are two sources of fats that organisms can use to obtain energy: from consumed dietary fats and from stored fat. [5] Vertebrates (including humans) use both sources of fat to produce energy for organs such as the heart to function. [6]
