Multiple Choice

How does a red blood cell attach oxygen to itself?

By storing oxygen in the nucleus of the cell

By binding oxygen to hemoglobin molecules within the cell

By dissolving oxygen directly into the cytoplasm

By using enzymes to chemically react with oxygen

Verified step by step guidance

Understand the structure of a red blood cell: Red blood cells are specialized cells that lack a nucleus and organelles, which allows more space for hemoglobin molecules.

Learn about hemoglobin: Hemoglobin is a protein found in red blood cells that is responsible for transporting oxygen from the lungs to the rest of the body.

Explore the binding process: Oxygen binds to the iron atoms in the heme groups of hemoglobin molecules. Each hemoglobin molecule can carry up to four oxygen molecules.

Consider the role of hemoglobin: Hemoglobin's ability to bind and release oxygen is crucial for maintaining oxygen supply to tissues and organs throughout the body.

Recognize the incorrect options: Oxygen is not stored in the nucleus (as red blood cells lack a nucleus), nor is it dissolved directly into the cytoplasm or chemically reacted with enzymes in this context.
