Verified step by step guidance

Understand the role of hemoglobin: Hemoglobin is a protein in red blood cells responsible for transporting oxygen from the lungs to tissues and carbon dioxide back to the lungs.

Review the terms provided: Oxyhemoglobin refers to hemoglobin bound to oxygen, Deoxyhemoglobin refers to hemoglobin not bound to oxygen, Methemoglobin is a form of hemoglobin where iron is oxidized and cannot bind oxygen, and Carbaminohemoglobin refers to hemoglobin bound to carbon dioxide.

Focus on the question: The problem asks for the term describing hemoglobin that is not transporting any oxygen. This means hemoglobin is in its unbound state with respect to oxygen.

Match the correct term: Based on the definitions, Deoxyhemoglobin is the term that refers to hemoglobin not transporting any oxygen.

Conclude the reasoning: The correct answer is Deoxyhemoglobin because it specifically describes hemoglobin in its oxygen-free state, unlike the other terms which describe hemoglobin bound to oxygen, carbon dioxide, or in an oxidized form.
