A pharmaceutical company tries to develop a drug that improves tissue oxygenation by increasing the percentage of oxygen that is
released from hemoglobin during its passage through the capillaries of extrapulmonary tissues. This drug, it is hoped, would become a popular doping agent for athletes. The company should try a drug that:________.
a) Binds to ion channels in the red blood cell (RBC) membrane, thereby increasing the intracellular pH value
b) Binds to the R conformation of hemoglobin, but not the T conformation
c) Binds to the heme iron
d) Inhibits the degradation of 2, 3 - BPG, thereby increasing its concentration in erythrocytes.
e) Prevents binding of CO2 to hemoglobin
Explain your reasoning for each of the answers above (a through e).
D. Inhibits the degradation of 2,3-BPG, thereby increasing its concentration in erythrocytes
Explanation:
A pharmaceutical company trying to develop a drug that improves tissue oxygenation by increasing the percentage of oxygen that is released from hemoglobin during its passage through the capillaries of extrapulmonary tissues. This drug, it is hoped, would become a popular doping agent for athletes.This means that the company should try a drug that Inhibits the degradation of 2,3-BPG( 2,3-Bisphosphoglycerate) , thereby increasing its concentration in erythrocytes
An ecological community can be described as all the different species of organisms i.e all the different plants and animals, living in a particular habitat at a specified time. An ecological community will consist of: Predators: Organisms which feed on other organisms.
