    Mitochondrion

    Organelle in eukaryotic cells responsible for respiration

    A mitochondrion is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi. Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate, which is used throughout the cell as a source of chemical energy. They were discovered by Albert von Kölliker in 1857 in the voluntary muscles of insects. Meaning a thread-like granule, the term mitochondrion was coined by Carl Benda in 1898. The mitochondrion is popularly nicknamed the "powerhouse of the cell", a phrase popularized by Philip Siekevitz in a 1957 Scientific American article of the same name. Some cells in some multicellular organisms lack mitochondria. The multicellular animal Henneguya salminicola is known to have retained mitochondrion-related organelles despite a complete loss of their mitochondrial genome. Wikipedia

    Nov 29, 2024Mitochondrion, organelle found in most eukaryotic cells, the primary function of which is to generate energy in the form of adenosine triphosphate. Mitochondria also store calcium for cell signaling activities, generate heat, and mediate cell growth and death. They typically are round to oval in shape.

    Mitochondria (singular: mitochondrion) are organelles within eukaryotic cells that produce adenosine triphosphate (ATP), the main energy molecule used by the cell. For this reason, the mitochondrion is sometimes referred to as "the powerhouse of the cell".

    The Mitochondrion Contains an Outer Membrane, an Inner Membrane, and Two Internal Compartments. Each mitochondrion is bounded by two highly specialized membranes, which have very different functions. Together they create two separate mitochondrial compartments: the internal matrix and a much narrower intermembrane space.
