What are the modes of transport in blood for glucose, amino acids, cholesterol, lipids, sodium chloride, and oxygen?
Understand the Problem
The image presents a table detailing the modes of transport for various substances in blood, explaining how each substance interacts with blood plasma based on its chemical properties.
Answer
Glucose, amino acids, and sodium chloride are dissolved in plasma; cholesterol and lipids in lipoproteins; oxygen is attached to hemoglobin.
Glucose and amino acids are dissolved in blood plasma. Cholesterol and lipids are transported in lipoprotein complexes. Sodium chloride is dissolved in plasma. Oxygen is mostly carried by hemoglobin.
Answer for screen readers
Glucose and amino acids are dissolved in blood plasma. Cholesterol and lipids are transported in lipoprotein complexes. Sodium chloride is dissolved in plasma. Oxygen is mostly carried by hemoglobin.
More Information
Glucose, amino acids, and sodium chloride dissolve easily due to their polar nature. Lipids and cholesterol require lipoproteins because they are nonpolar. Oxygen uses hemoglobin for efficient transport since it is not very soluble.
Tips
A common mistake is assuming all substances dissolve directly in plasma. Remember that nonpolar molecules need carriers.
