Verified step by step guidance

Understand the oxyhemoglobin dissociation curve: This curve represents the relationship between the partial pressure of oxygen (pO2) and the saturation of hemoglobin with oxygen. It is typically sigmoidal in shape.

Identify factors affecting the curve: Metabolically active tissues produce more carbon dioxide, increase temperature, and lower pH due to increased metabolic activity. These factors influence the curve.

Consider the Bohr effect: The Bohr effect describes how increased carbon dioxide and decreased pH (more acidic conditions) lead to hemoglobin releasing oxygen more readily, causing a rightward shift in the curve.

Analyze the impact of temperature: Higher temperatures, often found in metabolically active tissues, also cause hemoglobin to release oxygen more easily, contributing to a rightward shift in the curve.

Conclude the effect on the curve: Given the conditions around metabolically active tissues (increased CO2, lower pH, higher temperature), the oxyhemoglobin dissociation curve shifts to the right, facilitating oxygen release to tissues.
