Summary Introduction

Introduction:

The blood carries CO2 and O2 from and to the tissues in the body. Hemoglobin is the protein responsible for the transport of oxygen.

How does the concentration of 2,3 BPG affect hemoglobin's P50 for oxygen? select the correct answer A) BPG binds to the N-terminus of Hemoglobin's alpha 2 subunit and increase hemoglobin's P50 for oxygen. B) BPG binds to the heme blocking oxygen's ability to bind and lowering hemoglobin's P 50. C) As the BPG increases hemoglobin's P50 for oxygen increase. D) As the BPG increases hemoglobin's P50 for oxygen decreases. E) BPG does not affect hemoglobin's P50 for oxygen
Which of the following concerning hemoglobin is true? a) BPG decreases at high altitudes and causes more O2 offloading in tissues b) As pH increases, [CO2] increases in tissues, causing more O2 release in tissue c) The R state is stabilized by CO2 binding, whereas the T state is stabilized by O2 binding d) About 38% of oxygen dissociates from hemoglobin in tissues e) Hemoglobin has a higher affinity for oxygen than carbon monoxide My guess is D.
