  2. Homeostasis - Wikipedia

    en.wikipedia.org/wiki/Homeostasis

    In biology, homeostasis (British also homoeostasis; / h ɒ m i oʊ ˈ s t eɪ s ɪ s,-m i ə-/) is the state of steady internal physical and chemical conditions maintained by living systems. [1] This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance , being kept ...

  3. Metabolism - Wikipedia

    en.wikipedia.org/wiki/Metabolism

    Metabolism (/ m ə ˈ t æ b ə l ɪ z ə m /, from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms.The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the ...

  4. Steady state - Wikipedia

    en.wikipedia.org/wiki/Steady_state

    In chemistry, a steady state is a more general situation than dynamic equilibrium. While a dynamic equilibrium occurs when two or more reversible processes occur at the same rate, and such a system can be said to be in a steady state, a system that is in a steady state may not necessarily be in a state of dynamic equilibrium, because some of ...

  5. Acid–base homeostasis - Wikipedia

    en.wikipedia.org/wiki/Acid–base_homeostasis

    t. e. Acid–base homeostasis is the homeostatic regulation of the pH of the body's extracellular fluid (ECF). [1] The proper balance between the acids and bases (i.e. the pH) in the ECF is crucial for the normal physiology of the body—and for cellular metabolism. [1] The pH of the intracellular fluid and the extracellular fluid need to be ...

  6. Cellular respiration - Wikipedia

    en.wikipedia.org/wiki/Cellular_respiration

    Cellular respiration is the process by which biological fuels are oxidised in the presence of an inorganic electron acceptor, such as oxygen, to produce large amounts of energy and drive the bulk production of ATP. Anaerobic respiration is used by microorganisms, either bacteria or archaea, in which neither oxygen (aerobic respiration) nor ...

  7. Bioenergetics - Wikipedia

    en.wikipedia.org/wiki/Bioenergetics

    Bioenergetics is the part of biochemistry concerned with the energy involved in making and breaking of chemical bonds in the molecules found in biological organisms. [5] It can also be defined as the study of energy relationships and energy transformations and transductions in living organisms. [6] The ability to harness energy from a variety ...

  8. Metabolic pathway - Wikipedia

    en.wikipedia.org/wiki/Metabolic_pathway

    t. e. In biochemistry, a metabolic pathway is a linked series of chemical reactions occurring within a cell. The reactants, products, and intermediates of an enzymatic reaction are known as metabolites, which are modified by a sequence of chemical reactions catalyzed by enzymes. [1]: 26 In most cases of a metabolic pathway, the product of one ...

  9. Steady state (biochemistry) - Wikipedia

    en.wikipedia.org/wiki/Steady_state_(biochemistry)

    See also: Steady state (chemistry) In biochemistry, steady state refers to the maintenance of constant internal concentrations of molecules and ions in the cells and organs of living systems. [ 1 ] Living organisms remain at a dynamic steady state where their internal composition at both cellular and gross levels are relatively constant, but ...
