  2. Ecosystem respiration - Wikipedia

    en.wikipedia.org/wiki/Ecosystem_respiration

    Ecosystem respiration is the production portion of carbon dioxide in an ecosystem's carbon flux, while photosynthesis typically accounts for the majority of the ecosystem's carbon consumption. [3] Carbon is cycled throughout the ecosystem as various factors continue to uptake or release the carbon in different circumstances.

  3. Soil respiration - Wikipedia

    en.wikipedia.org/wiki/Soil_respiration

    Soil respiration refers to the production of carbon dioxide when soil organisms respire. This includes respiration of plant roots, the rhizosphere, microbes and fauna.. Soil respiration is a key ecosystem process that releases carbon from the soil in the form of CO 2.

  4. Chlororespiration - Wikipedia

    en.wikipedia.org/wiki/Chlororespiration

    This cyclic pathway also allows electrons to re-enter the PQ pool through NAD(P)H enzyme activity and production, which is then used to supply ATP molecules (energy) to plant cells. [7] A diagram depicting newly discovered molecules (PTOX and the NDH complex) as part of the chlororespiratory process in higher order plants like Rosa Meillandina.

  5. Respiration (physiology) - Wikipedia

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

    In mammals, physiological respiration involves respiratory cycles of inhaled and exhaled breaths. Inhalation (breathing in) is usually an active movement that brings air into the lungs where the process of gas exchange takes place between the air in the alveoli and the blood in the pulmonary capillaries.

  6. Respiratory system - Wikipedia

    en.wikipedia.org/wiki/Respiratory_system

    The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...

  7. Community respiration - Wikipedia

    en.wikipedia.org/wiki/Community_respiration

    The elements can be isolated by using the Electron Transport System (ETS) as a respiratory index and measuring that, which would indicate the rate of cellular respiration. [7] CR can be used in conjunction with other ecological indexes such as Dissolved oxygen concentration (DO), Gross Primary Production (GPP), Nutrient availability, Light ...

    Adding plant-derived ceramides (or phytoceramides) to your skin care routine can help replenish skin ceramide levels, promoting healthy, hydrated skin. Pro tip: Don't forget about hydration.

  9. Plant physiology - Wikipedia

    en.wikipedia.org/wiki/Plant_physiology

    The ripening of fruit and loss of leaves in the winter are controlled in part by the production of the gas ethylene by the plant. Finally, plant physiology includes the study of plant response to environmental conditions and their variation, a field known as environmental physiology. Stress from water loss, changes in air chemistry, or crowding ...
