What are the components of the thin filaments of a muscle cell?
Actin, Tropomyosin and troponin.
Thin filament which is
-
Actin
#to# The thin filaments are composed chiefly of actin proteins. That's why these filaments are also called as actin filaments. The actin molecules are arranged in to chains. This chains twist around each other like twisted double strand of pearls. -
Tropomyosin
#to# Two strands of another protein twist around actin, This protein is tropomyosin. -
Troponin
#to# This is another protein in thin filament. It is actually#3# polypeptide complex:#"troponin I, troponin C & troponin T"# . Out of these: troponin I binds to actin and troponin T binds to tropomyosin. Troponin C binds calcium ions#(Ca^(2+))# in order to start muscle contraction.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
