Taking Professor Yaffe's advice to push models to their limits, Cesar sets up a table and starts brainstorming how changing each variable alone, as well as in combination can alter oxygen-binding affinity. You can click or hover over a point on the curve to see the corresponding coordinates with your cursor. Reset by entering starting point values into the entry fields: pH=7.24, [2,3-BPG] =4.65mM, temperature 37C and pCO2=40mmHg Enter the P50 value for each scenario as a whole number.
