WebJan 19, 2024 · Some myosin molecules bind to cargo and use the cytoskeleton to transport materials within the cell. Myosin II specifically functions to drive contraction of a muscle cell and allow bodies to... 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.
