  2. Bioenergetics - Wikipedia

    en.wikipedia.org/wiki/Bioenergetics

    Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. [1] This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to ...

  3. Cell biology - Wikipedia

    en.wikipedia.org/wiki/Cell_biology

    A cell is the basic unit of life that is responsible for the living and functioning of organisms. [3] Cell biology is the study of the structural and functional units of cells. Cell biology encompasses both prokaryotic and eukaryotic cells and has many subtopics which may include the study of cell metabolism , cell communication , cell cycle ...

  4. Schweitzer Engineering Laboratories - Wikipedia

    Otter Tail initially used the SEL-21 for its fault location and event recording functions. SEL uses OTTER and TAIL as default passwords for their relays as an homage to their very first customer. In 1985, SEL built its first building and employed eleven people. In 2009, SEL became 100% employee-owned under an employee stock ownership plan (ESOP).

  5. Work unit - Wikipedia

    en.wikipedia.org/wiki/Work_unit

    A work unit or danwei (simplified Chinese: 单位; traditional Chinese: 單位; pinyin: dān wèi) is the name given to a place of employment in the People's Republic of China. The term danwei remains in use today, as people still use it to refer to their workplace.

  6. Cell (biology) - Wikipedia

    en.wikipedia.org/wiki/Cell_(biology)

    The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope.

  7. Unit cell - Wikipedia

    en.wikipedia.org/wiki/Unit_cell

    A primitive cell is a unit cell that contains exactly one lattice point. For unit cells generally, lattice points that are shared by n cells are counted as ⁠ 1 / n ⁠ of the lattice points contained in each of those cells; so for example a primitive unit cell in three dimensions which has lattice points only at its eight vertices is considered to contain ⁠ 1 / 8 ⁠ of each of them. [3]

  8. Evolution of cells - Wikipedia

    en.wikipedia.org/wiki/Evolution_of_cells

    Modern evidence suggests that early cellular evolution occurred in a biological realm radically distinct from modern biology. It is thought that in this ancient realm, the current genetic role of DNA was largely filled by RNA, and catalysis was also largely mediated by RNA (that is, by ribozyme counterparts of enzymes).

  9. Cell physiology - Wikipedia

    en.wikipedia.org/wiki/Cell_physiology

    Cell physiology is the biological study of the activities that take place in a cell to keep it alive. The term physiology refers to normal functions in a living organism. [1] ...
