Verified step by step guidance

Understand the role of hemoglobin: Hemoglobin is a protein found in red blood cells, and its primary function is related to oxygen transport. It binds oxygen in the lungs and releases it in tissues where it is needed for cellular respiration.

Eliminate incorrect options: Review the provided choices and eliminate those that do not align with the known function of hemoglobin. For example, hemoglobin is not involved in the synthesis of amino acids, storage of genetic information, or catalysis of glucose breakdown in glycolysis.

Focus on oxygen transport: Hemoglobin contains iron ions in its heme groups, which allow it to bind oxygen molecules. This binding is reversible, enabling hemoglobin to pick up oxygen in the lungs and release it in tissues.

Relate to physiological processes: Oxygen transport is critical for aerobic respiration, where cells use oxygen to produce energy in the form of ATP. Hemoglobin ensures that oxygen is efficiently delivered to tissues throughout the body.

Confirm the correct answer: Based on the explanation, the primary function of hemoglobin is 'Transport of oxygen from the lungs to tissues,' which matches the correct answer provided in the problem.
