Problem 4 In class, we 1.0 discussed multiple ways that hemoglobin achieves an enhanced difference between the fractional saturation of oxygen from lungs to tissues (Ylungs-Ytissues). Lamprey hemoglobin binds oxygen in a monomeric form, but using the Bohr effect, is still is able to transport 60% of its oxygen binding capacity from pO2 = 80 torr to 20 torr between its oxygen absorbing organ and the tissues. Human Hemoglobin Curve 20 40 60 80 100 PO₂ By drawing two curves on the figure at right showing the human tetrameric hemoglobin curve, show how Lamprey hemoglobin can achieve this oxygen transport. Indicate on each curve the conditions that are associated with it.

question: Mammalian respiration is described as "negative pressure breathing" because intra-alveolar pressure is negative during both inspiration and expiration. answer should clearly state whether or not the statement is correct and then concisely explain why. the answer should be like more than three but less than 5 sentences and address all of the points in the statement. Here is an example: Both transmembrane carrier proteins and transmembrane channel proteins can mediate active transport of a hydrophilic solute through a cell plasma membrane. This statement is incorrect. Movement of a solute through a channel protein is always passive, whereas carrier-mediated transmembrane transport can be either passive or active. A transmembrane channel protein creates a pore through the membrane allowing for simple diffusion of a hydrophilic solute down a concentration gradient through the membrane. In contrast, transmembrane carrier protein interacts with and 'escorts' a hydrophilic…

Few question on what did, How did you calculate the pO2 of the patient as 65? Additionally for the percent saturation if the patient's Kd is 48 shouldn't the first half of part a be divided by (48+65)? Why is it divided by 58+pO2? Finally what is meant by oxygen binding cooperativety in the problem?
