Verified step by step guidance

Understand the role of red blood cells: Red blood cells are responsible for transporting oxygen from the lungs to the tissues and returning carbon dioxide from the tissues to the lungs.

Identify the molecule responsible for oxygen transport: In red blood cells, oxygen is primarily transported by a specific protein molecule.

Learn about hemoglobin: Hemoglobin is a protein found in red blood cells that has a high affinity for oxygen. It consists of four subunits, each containing an iron atom that can bind to an oxygen molecule.

Differentiate between hemoglobin and other proteins: Myoglobin is a similar protein found in muscle tissue, but it is not involved in oxygen transport in the blood. Fibrinogen and albumin are proteins with different functions, unrelated to oxygen transport.

Conclude with the correct molecule: Based on the function and structure of hemoglobin, it is the molecule that binds oxygen in red blood cells, facilitating its transport throughout the body.
