Verified step by step guidance

Understand the structure and function of microfilaments in the cell. Microfilaments are part of the cytoskeleton, which provides structural support and plays a role in cell movement.

Identify the primary protein that composes microfilaments. Microfilaments are primarily composed of actin proteins, which are globular proteins that polymerize to form long, thin fibers.

Differentiate between the types of proteins that make up the cytoskeleton. While microfilaments are made of actin, microtubules are composed of tubulin proteins, and intermediate filaments are made of various proteins.

Consider the role of actin in cellular processes. Actin is involved in muscle contraction, cell division, and cell signaling, highlighting its importance in cellular function.

Review the options provided and match them with the known composition of microfilaments. The correct choice is actin proteins, as they are the repeating subunits that form microfilaments.
