Question

match each protein with the appropriate filament. labels drop zones reset all tropomyosin thick filaments (1/3) thin filaments (2/3) neither thick nor thin filaments (3/3) myosin dystrophin actin sites elastic filament troponin myosin heads

Explanation:

Tropomyosin and troponin are part of thin - filaments. Myosin is the main protein of thick - filaments. Dystrophin is involved in linking the muscle cytoskeleton to the extracellular matrix and is neither a thick nor thin filament protein. Active sites are on the thin filaments. Elastic filaments are made of titin and are neither thick nor thin filaments in the traditional sense. Myosin heads are part of the myosin molecules in thick filaments.

Answer:

Tropomyosin: Thin Filaments
Myosin: Thick Filaments
Dystrophin: Neither Thick Nor Thin Filaments
Active sites: Thin Filaments
Elastic filament: Neither Thick Nor Thin Filaments
Troponin: Thin Filaments
Myosin heads: Thick Filaments
