WebApr 6, 2024 · These fibers are singular protein dense cells which contain many nuclei, mitochondria and endoplasmic reticulum. Each fiber is surrounded by a plasma membrane called the sarcolemma, and inside this sits the sarcoplasm, a gelatin-like substance which separates myofibrils and helps maintain the shape of the cell. WebType 1 (“slow twitch”) fibers contain more mitochondria, which means they can produce more energy and are better for long, aerobic activities. Type 2 (“fast twitch”) fibers, on the other hand, are suited for short, fast bursts …
WebDec 23, 2024 · Why do fast-twitch fibers have more glycogen? They do not require as many mitochondria per cell as they are less reliant on anaerobic respiration. Instead they express higher levels of cytoplasmic glycolytic enzymes to allow fast glycolysis in anaerobic respiration. They have large glycogen stores.
