  2. Sarcoplasm - Wikipedia

    en.wikipedia.org/wiki/Sarcoplasm

    Sarcoplasm is the cytoplasm of a muscle cell. It is comparable to the cytoplasm of other cells, but it contains unusually large amounts of glycogen (a polymer of glucose), myoglobin, a red-colored protein necessary for binding oxygen molecules that diffuse into muscle fibers, and mitochondria.

  3. Myoglobin - Wikipedia

    en.wikipedia.org/wiki/Myoglobin

    Myoglobin is found in Type I muscle, Type II A, and Type II B; although many older texts describe myoglobin as not found in smooth muscle, this has proved erroneous: there is also myoglobin in smooth muscle cells. [14] Myoglobin was the first protein to have its three-dimensional structure revealed by X-ray crystallography. [15]

    “Slow-twitch muscle fibers contain high levels of mitochondria and myoglobin, an oxygen-binding protein that can release oxygen for energy production during exercise,” Scott explains.

  5. Muscle cell - Wikipedia

    en.wikipedia.org/wiki/Muscle_cell

    Broadly there are two types of muscle fiber performing in muscle contraction, either as slow twitch or fast twitch . A single muscle such as the biceps brachii in a young adult human male contains around 253,000 muscle fibers. [11] Skeletal muscle fibers are the only muscle cells that are multinucleated with the nuclei usually referred to as ...

  6. Skeletal muscle - Wikipedia

    en.wikipedia.org/wiki/Skeletal_muscle

    Type II muscle fibers rely on glucogenesis for energy during anaerobic exercise. [80] During anaerobic exercise, type II fibers consume little oxygen, protein and fat, produce large amounts of lactic acid and are fatigable. Many exercises are partially aerobic and anaerobic; for example, soccer and rock climbing.

  8. Myofibril - Wikipedia

    en.wikipedia.org/wiki/Myofibril

    A myofibril (also known as a muscle fibril or sarcostyle) [1] is a basic rod-like organelle of a muscle cell. [2] Skeletal muscles are composed of long, tubular cells known as muscle fibers, and these cells contain many chains of myofibrils. [3] Each myofibril has a diameter of 1–2 micrometres. [3]
