I now know the structure difference between myoglobin and hemoglobin , however which exctaly structure difference make myglobin become a oxygen storage ? and not a oxygen transport?? Be specific! details describe how the structure connect to their role. also which exctaly structure difference make hemoglobin become better oxygen transport?? I need the specific structure that contribute to their unique role. I KNOW THE STRUCTURE DIFFERENCE , but don't understand which specific part make myoglobin only bind to oxygen, and not release oxygen

The inner leaflet (monolayer) of the human erythrocyte membrane consists predominantly of phosphatidylethanolamine and phosphatidylserine. The outer leaflet consists predominantly of phosphatidylcholine and sphingomyelin. Although the phospholipid components of the membrane can diffuse in the fluid bilayer, this sidedness is preserved at all times. How?

One of the important uses of the Nernst equation is in describing the flow of ions across plasma membranes. Ions move under the influence of two forces: the concentration gradient (given in electrical units by the Nernst equation) and the electrical gradient (given by the membrane voltage). This is summarized by Ohms law: Ix=Gx(VmEx) which describes the movement of ion x across the membrane. I is the current in amperes (A); G is the conductance, a measure of the permeability of x, in Siemens (S), which is I/V;Vm is the membrane voltage; and Ex is the equilibrium potential of ion x. Not only does this equation tell how large the current is, but it also tells what direction the current is flowing. By convention, a negative value of the current represents either a positive ion entering the cell or a negative ion leaving the cell. The opposite is true of a positive value of the current. a. Using the following information, calculate the magnitude of Na [ Na+ ]0=145mM,[ Na+ ]i=15mM,Gna+=1nS,Vm=70mV b. Is Na+ entering or leaving the cell? c. Is Na+ moving with or against the concentration gradient? Is it moving with or against the electrical gradient?

The primary and tertiary structures of hemoglobin and myoglobin are very similar and both contain the 'heme' group as an oxygen-binding prosthetic group. However this There are important functional differences between the two proteins. Hemoglobin oxygen transport protein, myoglobin functions as oxygen storage protein.

The small capillaries in the lungs are in close contact with the alveoli. A red blood cell takes up oxygen during the 0.5 s that it squeezes through a capillary at the surface of an alveolus. What is the diffusion time for oxygen across the 1-μm -thick membrane separating air from blood? Assume that the diffusion coefficient for oxygen in tissue is 2×10−11m2/s. Give your answer to 1 significant figure.
Nitric oxide (NO) is a gaseous molecule with lipid solubility similar to that of O2 and CO2. Endothelial cells lining arteries use NO to signal surrounding smooth muscle cells to relax, thereby increasing blood flow. What mechanism or mechanisms would transport NO from where it is produced in the cytoplasm of an endothelial cell into the cytoplasm of a smooth muscle cell, where it acts?
