Cells can be described as having a cytoskeleton of internal structures that contribute to the shape, organization and movement o
f the cell. Which of the following is a part of the cytoskeleton? Group of answer choices
A. glycogen
B. cellulose microfibrils
C. microfilaments
D. calcium depositories
Explanation: Microfilaments, also called actin filaments, are protein filaments in the cytoplasm of eukaryotic cells that form part of the cytoskeleton. They are primarily composed of polymers of actin, but are modified by and interact with numerous other proteins in the cell. Microfilaments, or actin filaments, are the thinnest filaments of the cytoskeleton and are found in the cytoplasm of eukaryotic cells. The polymers of these linear filaments are flexible but still strong, resisting crushing and buckling while providing support to the cell.
