Thin myofilaments are made up of the protein
WebThin myofilaments are composed of 3 types of protein: ACTIN, TROPONIN, and TROPOMYOSIN. The actin molecules (or G-actin as above) are spherical and form long chains. Each thin myofilament contains two such chains that coil around each other. TROPOMYOSIN molecules are lone, thin molecules that wrap around the chain of ACTIN. WebThe entire muscle is covered by a connective tissue sheath called the 6. The plasma membrane of a muscle fiber is called the 7. Thick filaments are comprised of 8. The A band is the band and comprises the length of 9. At the center of the l band is the which anchors the thin myofilaments. 10.
