Which property of connective tissue is fundamental to its function of binding tissues and organs? cells that contain actin and myosin mostly made of protein fibers regenerative properties tightly packed cells
cells that contain actin and myosin ATP is the coenzyme, which is used by the cells to transfer energy to the cell when a muscle cell demands energy to contract. ATP is short for Adenosine Triphosphate and is critical for muscles to contract. APT prepares the myosin to bind with actin - it moves the myosin to a high energy state ready to move. The myosin is the protein that converts the chemical energy, ATP, into mechanical energy. This cycle keeps on repeating itself and the muscle expands and contracts.
