"Get the book, even if u dont go through the questions just read the answers and highlight stuff you dont know. In my opinion its abridged version of any biology book you can get your hands on."
Open to criticisms. Who agrees and who doesn't? 😎
Don't blindly memorize the answers in destroyer. The best method is to read about the topic the answer choice is from in either a text book, wikipedia, kaplan's book or AP Cliff's Bio.
Do all the questions, no reason not to.
ap cliff's biology. There are a billion topics on this.
Has to deal with the bohr effect.
CO2 + H2O -> H2CO3 -> H+ + HCO3-
Increase in CO2 leads to increase concentration of H+ and a lower pH.
Here is the equation for hemoglobin in the tissues
H+ + HBO2 -> HHb+ + O2
Now if you combine both reactions it is easier to see how the Bohr Effect affects hemoglobin transport.
In the tissues the equation is :
HbO2 + CO2 + H2O + H+ -> HHb+ + O2 + HCO3-
Using Le Chatlier's Principles: an increase in H+ causes a shift right. In other words hemoglobin releases more oxygen at lower pHs.
This is wonderful for the body because the pH of the tissues are more acidic than that of the lungs. This enables hemoglobin to unload oxygens at the tissue and bind oxygen at the lungs.
This also shows that the body is all about chemistry.
You were on the right track. I hope this helps you out.
