Which of the following is true about intermediate filaments?
A)They are named based on their location in cells between actin microfilaments and microtubules.
B)All cells express the same class II cytoplasmic intermediate filament proteins.
C)Staggered,antiparallel tetramers give intermediate filaments strength.
D)Acidic and basic keratins provide dynamic paths on which organelles may travel.

Question

Quizplus · Accepted Answer

Intermediate filaments are named for their intermediate size, between actin microfilaments and microtubules, but not based on their location in cells. Different cells express different classes of intermediate filament proteins. Staggered, antiparallel tetramers form the basic structure of intermediate filaments, which gives them their strength. Keratins are a specific type of intermediate filament protein found in epithelial cells, and they do not provide dynamic paths for organelles.
