Final answer:
The question is based on Biology and discusses how hemoglobin in red blood cells and synthetic oxygen carriers increase the concentration of oxygen, facilitating transport and supporting energy needs in multicellular organisms.
Step-by-step explanation:
The subject of this question is Biology and it pertains to how oxygen (O₂) is transported in the blood. Due to the low Henry's law constant for O₂ in water, the dissolved oxygen levels are insufficient to meet the energy needs of multicellular organisms. Human red blood cells contain hemoglobin, which binds O₂ and significantly enhances its concentration in the blood. While the concentration of dissolved O₂ in blood serum is only 0.010 mM, the presence of hemoglobin increases it to 8.8 mM. Additionally, synthetic oxygen carriers like those based on fluorinated alkanes have high Henry's law constants for O₂ and can substitute for whole blood in emergencies, providing dissolved oxygen levels akin to normal blood.
