B)Most oxygen is carried by the iron in blood plasma. C)As the pH of tissues decreases, more oxygen is released from hemoglobin. D)Increased CO₂ in the blood makes the blood pH more alkaline. E)As the temperature of tissues increases, less oxygen is released from hemoglobin. F)Too much CO₂ in the blood results in hypoxia.

Question

A) Most CO₂ is carried in the blood as bicarbonate ions. This statement is true. Most of the carbon dioxide produced by cells is converted to bicarbonate ions before it is transported in the blood. B) Most oxygen is carried by the iron in blood plasma. This statement is false. Oxygen is primarily carried by hemoglobin molecules in red blood cells, not by iron in blood plasma. C) As the pH of tissues decreases, more oxygen is released from hemoglobin. This statement is true. When the pH of tissues decreases (becomes more acidic), hemoglobin releases more oxygen to those tissues. D) Increased CO₂ in the blood makes the blood pH more alkaline. This statement is false. Increased carbon dioxide in the blood can lead to a lower pH (more acidic), not a more alkaline pH. E) As the temperature of tissues increases, less oxygen is released from hemoglobin. This statement is false. As the temperature of tissues increases, hemoglobin actually releases more oxygen to those tissues. F) Too much CO₂ in the blood results in hypoxia. This statement is misleading. Hypoxia refers to a lack of oxygen in the tissues, not an excess of carbon dioxide in the blood. However, high levels of carbon dioxide in the blood can indicate respiratory or metabolic problems that may lead to hypoxia.
