CHEMISTRY 445 – Myoglobin and Hemoglobin Watch the lecture videos on myoglobin and hemoglobin. Answers to some of the reading guide questions can be easily found in the videos, while others will require synthesis of information. You may need to consult a biochemistry text for additional information. Concepts related to synthesis questions will be discussed further in class; you are not expected to fully grasp all concepts from the reading/videos prior to class. Reading Questions: 1. What is the function of hemoglobin? Is it an enzyme? How do you know? Pickup oxygen in the lungs to release it to the tissue. Hemoglobin will be consider an protein, since it binds to oxygen 2. Compare and contrast hemoglobin and myoglobin. Consider both structure and function. Myoglobin is hyperbolic curve Total oxygen saturation doesn’t change much between lungs and tissue. Myoglobin is oxygen storage Hemoglobin is sigmodal curve Saturation of hemoglobin in tissues is different from the saturation levels in the lungs. Pick up oxygen in the lungs and release in the tissue

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
