Which of the following is not true about slow twitch muscle fibers better suited for aerobic activities have more mitochondria than fast twitch fibers have more creatine kinase are also called type I fibers none – all the above are true. 273. WebRecall that it is the myosin head that splits ATP. Fast-twitch fibers have a more rapid ATPase (splitting of ATP into ADP + P i) ability. Fast-twitch fibers also pump Ca 2+ ions back into the sarcoplasmic reticulum very quickly, so these cells have much faster twitches than the slower variety. Thus, fast-twitch fibers can complete multiple ... WebSep 26, 2024 · Type I fibers are a “slow twitch” muscle fiber. They are called slow twitch as they generate force at a slower rate comparably with type II. These fibers also have a slower rate of fatigue.
