2. Which statement best describes an allosteric antagonist?
- Drug that acts competitively and irreversibly to block the actions of another drug on the same active site
- Drug that binds to a receptor at a site distinct from the active site
- The measurement of the relative safety of a drug
- Causes an action opposite to that of the agonist
3. Which example describes Pharmacodynamics?
- The process of phase I and phase II by the liver to break down drugs into more polar metabolites
- Drug stimulates a cell signal, which induces cellular signal transduction, resulting in a biological effect
- Is when a cell engulfs a drug molecule - better known as endocytosis
- According to the size of the drug molecules, the cells allow for rapid or slow absorption via means of a specific type of diffusion
4. Which statement best describes partial agonists?
- Causes an action opposite to that of the agonist
- A drug that causes as opposing biological response to another drug upon activation of the cell receptor
- Drugs that bind to and activate a given receptor, but have only partial efficiency at the receptor relative to a full agonist
- Drugs that blocks the actions of another drug, had it activated the cell receptor
5. What information is false about EC50 values?
- A drug with a higher EC50 value is worse than a drug with a lower EC50 value
- The potency of a drug can be observed on a curve where the EC50 value is lower than another drug for the same function
- Concentration of a drug that gives half maximum pharmaceutical response
- A drug with a lower EC50 value is worse than a drug with a higher EC50 value
