6. O2/CO2 Transport

Study Guide

How are RBCs different from other cells?

How does their difference allow them to move through the vascular system?

What is the general structure of hgb?

Where on the molecule does O2 bind?

What are the types of hgb that we discussed?

How does oxygenation affect hgb affinity and binding?

What does subunit cooperativity mean?

What is the difference between O2 saturation and hgb content

How is the carrying-capacity of blood calculated?

Which has a greater effect on increasing the carrying capacity of blood, hemoglobin or oxygen saturation

Why is the curve steepest at the oxygen concentrations that are found in the body tissues?

What can cause a shift in the oxyhemoglobin dissociation curve? what does the shift allow to happen?

what are some situations that would result in a right-shift to the curve? Left shift?

How are the molecules of myoglobin and hemoglobin different? what do they respond to?

How are the curves of myoglobin and hemoglobin different

How is CO2 transport different from O2 transport? What are the methods of CO2 transport?

What is the process for loading CO2 into a RBC? what is the end product inside the RBC?

How does CO2 get out of the RBC at the lung for exchange?
