A patient with severe anemia requires multiple blood transfusions. Which consequence is most likely due to decreased levels of 2,3-BPG in stored blood affecting hemoglobin?

💡 Explanation

Decreased 2,3-BPG in stored blood increases hemoglobin's oxygen affinity, because 2,3-BPG normally reduces affinity, promoting oxygen release. Therefore, less oxygen is delivered to tissues; rather than enhanced CO2 transport or improved pH buffering, which are independent processes.

• Why does filtrate osmolality decrease in the ascending limb of Henle within the nephron?
• Why does forced exhalation worsen asthma symptoms during an attack?
• Why does cancer cell proliferation occur despite checkpoint activation when a growth factor receptor, like EGFR, has a mutation that causes constitutive dimerization?
• If a patient's thyroid gland contains adequate iodine but the peripheral tissues show decreased T3 production, which consequence follows?
• Following vaccination, what immunological mechanism causes long-term protection against a specific pathogen upon re-exposure?
• Why does hypothermia develop in elderly individuals exposed to moderately cool environments, despite intact thermoreceptors?
