D
Collagen fibers
검증된 단계별 안내1
Understand the role of the cytoskeleton in a cell: The cytoskeleton is a network of fibers that provides structural support, shape, and organization to the cell. It also plays a role in cell movement and division.
Identify the main components of the cytoskeleton: The cytoskeleton is primarily composed of three types of protein filaments: microtubules, actin filaments (also known as microfilaments), and intermediate filaments.
Examine the function of each component: Microtubules are involved in maintaining cell shape, intracellular transport, and cell division. Actin filaments are crucial for cell movement and muscle contraction. Intermediate filaments provide mechanical support and help maintain cell integrity.
Consider the role of collagen fibers: Collagen fibers are not part of the cytoskeleton. They are a major component of the extracellular matrix, providing structural support to tissues outside the cell.
Conclude which option is not a cytoskeleton component: Based on the understanding that collagen fibers are part of the extracellular matrix and not the cytoskeleton, identify collagen fibers as the correct answer to the question.
