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 ...
