WebTroponin itself does not regulate speed or force of contraction. Speed of contraction is determined by the type of muscle fiber. i.e. fast twitch fibers have faster ATPase activity and faster tension development as a result. Force of contraction is increased by shortened time between action potentials and the number of fibers recruited. WebFeb 7, 2024 · The main functions of actin filaments include: Forming a dynamic cytoskeleton to provide structural support to cells. Supporting and allowing cell motility.
