Which of the following is part of a thin myofilament?
A) ATP-binding site
B) Globular (G) actin
C) Calcium
D) Myosin
E) Sarcolemma
Thin Myofilament
A component of the muscle fiber responsible for muscle contraction, composed primarily of the protein actin.
Globular (G) Actin
A monomeric form of actin protein that can polymerize to form filamentous (F) actin, part of the cytoskeleton in cells.
ATP-Binding Site
A region on a protein where ATP (adenosine triphosphate) binds, often involved in energy transfer within cells.
