To discuss:
The interpretation of oxyhemoglobin dissociation curve, the reason for the shape of the graph and how it is used to show the amount of oxygen unloading as hemoglobin passes through a typical systemic tissue.
Introduction:
RBCs (red blood corpuscles) have a red pigment called as hemoglobin which helps in the transport of oxygen (O2) and carbon dioxide to and from the tissues. Hemoglobin is a complex protein, which has two chains alpha and beta chains. There are four heme groups and each heme is bound to an O2 molecule which is linked to a central ferrous ion. Therefore, one hemoglobin molecule can carry up to four O2 molecules. The O2 bound hemoglobin is called as oxyhemoglobin (HbO2).

What would be the protein needs of a man named Josh who exercises moderately and is the same age and size as Wayne? Josh is 5 ft, 8 in tall and weighs 183 lb. Round the number of grams to the nearest whole number. During calculations, use numbers rounded to the first decimal place. Because protein requirement is a range, please enter two numbers: lower and upper range values, respectively. Separate the lower and upper range values, in that order, by a comma. ___, ___ g ?arrow_forwardC MasteringHealth MasteringNu X session.healthandnutrition-mastering.pearson.com/myct/itemView?assignment ProblemID=17396422&attemptNo=1&offset=prevarrow_forward
- If left untreated, most HIV-infected individuals will develop AIDS. Current treatments are focused on highlyactive antiretroviral therapy (HAART). HAART usually consists of an orally delivered drug cocktail containingtwo different reverse transcriptase inhibitors and one other drug, such as a protease inhibitor. Question: Develop a pharmacokinetic model of HAART treatment. Consider all 3 drugs. Make sure to include adiagram that illustrates your thinking, state all assumptions, and define your variables. Whatparameters would you need to know to find the concentration of drug in the plasma? In the T cells?(You do not need to write out or solve any equations.)arrow_forwardnot use ai pleseaarrow_forward(A) 25 20 20 15 NPP (Mg C/ha/yr) 10 10 5 0 0 2,000 4,000 6,000 ECOLOGY 4e, Figure 20.11 (Part 1) 2017 Sinauer Associates, Inc.

If you add heterotrophic respiration and autotrophic respiration together and then subtract that value from gross primary productivity, then you have a more refined estimate of ecosystem carbon storage than NEE. Differential heating due to the earth's tilt generates the global wind AND oceanic circulation patternsarrow_forward1arrow_forward
