Chapter 42.4, Problem 3CC
Summary Introduction
To explain: The reason behind why nitroglycerin is preferred to relieve chest pain and used to treat heart disease patients.
Concept introduction:
Nitroglycerin is used as a vasodilator that opens blood vessels to improve blood flow. Angina results when there is imbalance between the oxygen supply and oxygen demand without a proportional increase in supply. The process of narrowing of arterioles is known as vasoconstriction. The process of relaxation of arterioles is known as vasodilatation.

It has beta-2 selective agonist activity.
It does not provide cardiac stimulation with its bronchodilatory effect.
It has lesser cardiac adverse effects as a selective alpha-1 antagonist.
It has a open-piperazine ring which renders it to be less cardiotoxic.
Each of the following statements briefly describes one of Hb an allosteric interactions. Which of the
statements below are false?
A drop in the [H+] of blood plasma would lead to a decrease Hb affinity for O₂.
An increase in the partial pressure of CO₂ in the tissues would lead to a decrease Hb affinity for O₂-
If you inhaled CO for an extended period of time, at partial pressures 1000 fold higher than normal indoor
atmospheric pressure, your body would have a difficult time delivering oxygen to your tissues.
When the partial pressure of oxygen is low within the atmosphere, your body responds by increasing the
biological activity of Hb's negative effectors.
2,3 BPG is an allosteric effector that decrease haemoglobin affinity for oxygen by stabilizing the T-state of deoxyhaemoglobin. This lead to the release of oxygen to cells and body tissues for use. H atom and CO2 are also allosteric effector and can do same.
