Verified step by step guidance

Identify the role of each molecule listed in the options: ATP, Myoglobin, Carbonic anhydrase, and Hemoglobin.

Understand that ATP (adenosine triphosphate) is primarily an energy carrier in cells, not directly involved in oxygen storage.

Recognize that Carbonic anhydrase is an enzyme that helps convert carbon dioxide and water into carbonic acid, playing a role in gas exchange and pH balance, not oxygen storage.

Consider Hemoglobin, which is a protein in red blood cells responsible for transporting oxygen from the lungs to the rest of the body, but it is not primarily an oxygen reserve.

Focus on Myoglobin, a protein found in muscle tissues that binds oxygen and acts as an oxygen reserve, releasing it during periods of high demand, such as muscle contraction.
