CHEM 3052 Exam I Review Questions & Answers 2023/2024 What is the difference between ΔG and ΔG'° of a chemical reaction? Describe, quantitatively, the relationship between them. - ANSWER-ΔG=ΔG'°+RT(ln(Keq)). ΔG'° is used in reactions under biochemical standard state. In general, when ATP hydrolysis is coupled to an energy-requiring reaction, the actual reaction often consists of the transfer of a phosphate group from ATP to another substrate, rather than an actual hydrolysis of ...

Katzung & Trevor's Pharmacology: Examination and Board Review INTRODUCTION 1. A 3-year-old is brought to the emergency department having just ingested a large overdose of tolbutamide, an oral antidiabetic drug. Tolbutamide is a weak acid with a pKa of 5.3. It is capable of entering most tissues, including the brain. On physical examination, the heart rate is 100/min, blood pressure 90/50 mm Hg, and respiratory rate 20/min. Which of the following statements about this case of tolb...
