Receptor Macromolecule whose biological function changes when a drug binds to it What are the link between chemical actions and biological function? Receptors Emax maximum effect of a drug What happens when Emax is reached? Emax occurs when all receptors are bound What is in indication that spare receptors are present? When Emax is reached before all receptors are bound Agonist has affinity for a receptor as well as intrinsic activity at the receptor ...

During normal inspiration, which of the following occurs? a. Alveoli at the apexes expand less than those at the bases. b. Alveoli at the apexes expand more than those at the bases. c. Alveoli at the bases and apexes expand almost equally. d. Alveoli at the bases expand less than those at the apexes. ANS: A Like perfusion, ventilation also is increased in the lung bases, with approximately four times as much ventilation going to the bases than to the apexes of the upright lung. DIF: Appl...

Acid-Base Titration Curves Questions and Answers Acid-Base Titration Curves Titration curves show how pH varies during titration Strong Acid-Strong Base Titration Curve 1) Strong Acid-Strong Base Titration Curve. Due to the nature of the log scale i.e. a ten fold change in the [H+] is required to result in a change in pH of only one unit. 2) The pH then increases much more rapidly, and between a pH of about 3.5 and 10.5, the curve is virtually vertical This is due to the fact that ...

Hb (hemoglobin) binds to CO (carbon monoxide) with a higher affinity than oxygen and stabilizes the R (relaxed) state True When hemoglobin changes from the T to the R, it has a high affinity for oxygen True 00:03 01:22 When hemoglobin changes from the R to T, it has a low affinity for oxygen True Cooperatively refers to structural changes that increases the affinity for oxygen in hemoglobin When the oxygen concentration is high, the heme shape is planar....
