  2. Oxidative phosphorylation - Wikipedia

    en.wikipedia.org/wiki/Oxidative_phosphorylation

    Under highly aerobic conditions, the cell uses an oxidase with a low affinity for oxygen that can transport two protons per electron. However, if levels of oxygen fall, they switch to an oxidase that transfers only one proton per electron, but has a high affinity for oxygen.

  3. Hyperoxia - Wikipedia

    en.wikipedia.org/wiki/Hyperoxia

    Excessive exposure to oxygen can lead to oxygen toxicity, also known as oxygen toxicity syndrome, oxygen intoxication, and oxygen poisoning.There are two main ways in which oxygen toxicity can occur: exposure to significantly elevated partial pressures of oxygen for a short period of time (acute oxygen toxicity), or exposure to more modest elevations in oxygen partial pressures but for a ...

  4. Cellular respiration - Wikipedia

    en.wikipedia.org/wiki/Cellular_respiration

    Aerobic respiration requires oxygen (O 2) in order to create ATP.Although carbohydrates, fats and proteins are consumed as reactants, aerobic respiration is the preferred method of pyruvate production in glycolysis, and requires pyruvate to the mitochondria in order to be oxidized by the citric acid cycle.

  5. Bioenergetic systems - Wikipedia

    en.wikipedia.org/wiki/Bioenergetic_systems

    The process that converts the chemical energy of food into ATP (which can release energy) is not dependent on oxygen availability. During exercise , the supply and demand of oxygen available to muscle cells is affected by duration and intensity and by the individual's cardio respiratory fitness level. [ 1 ]

    Chioggia beets, also known as "Candystripe" or "Bull's eye" look like a typical red beet on the outside, but inside contain concentric rings of white and pink, which can add a dramatic flair to ...

  8. Respiratory quotient - Wikipedia

    en.wikipedia.org/wiki/Respiratory_quotient

    The respiratory quotient (RQ or respiratory coefficient) is a dimensionless number used in calculations of basal metabolic rate (BMR) when estimated from carbon dioxide production. It is calculated from the ratio of carbon dioxide produced by the body to oxygen consumed by the body, when the body is in a steady state.

    Research using animals has previously shown that nitrates can turn white fat storage cells into brown fat cells which are easier to burn off. Scientists to study if beetroot can help people with ...
