Verified step by step guidance1
Understand the role of plasma proteins in the blood. Plasma proteins have various functions including transport, immune defense, and clotting.
Identify the function of each listed protein: Transferrin transports iron, Albumin maintains osmotic pressure, Immunoglobulin G (IgG) is involved in immune response.
Recall that blood clotting requires a protein that can form a mesh to stop bleeding, which is the role of Fibrinogen.
Recognize that Fibrinogen is converted into fibrin during the clotting process, forming a stable clot to prevent blood loss.
Conclude that among the options, Fibrinogen is the essential plasma protein for blood clotting.
