Many students upload their own worked solutions to Course Hero. While not official, they can be useful if cross-checked. Beware of occasional miscalculations.

7. Sample Problem (Full Solution Excerpt – Chapter 3: Thermodynamics)

Problem: The hydrolysis of ATP to ADP + Pi under standard conditions has ΔG°' = -30.5 kJ/mol. In a resting muscle cell, [ATP] = 8 mM, [ADP] = 10 μM, [Pi] = 4 mM, T = 298 K. Calculate the actual ΔG. Is the reaction spontaneous?

Solution (as presented in manual):

1. Write the reaction: ATP + H₂O → ADP + Pi
2. Recall: ΔG = ΔG°' + RT ln ( [ADP][Pi] / [ATP] ) (Note: [H₂O] is omitted because it is solvent, ~55 M, effectively constant)
3. Convert concentrations to M (molarity): [ATP] = 8 × 10⁻³ M, [ADP] = 10 × 10⁻⁶ = 1 × 10⁻⁵ M, [Pi] = 4 × 10⁻³ M
4. Calculate the ratio Q = (1e-5 × 4e-3) / (8e-3) = (4e-8) / (8e-3) = 0.5 × 10⁻⁵ = 5 × 10⁻⁶
5. Compute RT ln Q: R = 8.314 J/mol·K, T = 298 K → RT = 2477.6 J/mol ≈ 2.48 kJ/mol ln(5 × 10⁻⁶) = ln(5) + ln(10⁻⁶) = 1.609 – 13.816 = –12.207 RT ln Q = 2.48 × (-12.207) ≈ –30.3 kJ/mol
6. Add ΔG°': ΔG = –30.5 + (–30.3) = –60.8 kJ/mol
7. Conclusion: Highly spontaneous, far more exergonic than standard conditions due to low [ADP] (mass action effect). This explains why ATP hydrolysis can drive unfavorable reactions in the cell.

6. Comparison to Other Major Textbooks' Solutions

| Textbook | Solutions Approach | |----------|--------------------| | Mathews 4th | Rigorous, quantitative, physical chemistry heavy. Minimal hand-holding. | | Lehninger 7th | More accessible, step-by-step, but less depth in thermodynamics. | | Voet & Voet 4th | Very mathematical, similar to Mathews, but solutions manual is harder to find. | | Stryer 9th | Focuses on conceptual problems; calculation-based problems are fewer. |

• AK Lectures – Excellent for Mathews-style thermodynamics and kinetics.
• Ninja Nerd – Overly detailed but great for pathways like gluconeogenesis.
• Oregon State University’s BB 450/550 – Free video lectures that follow a syllabus nearly identical to Mathews.

Part 1: The Structure of the Mathews 4th Edition – What You’re Really Solving

Before diving into solutions, you need to map the terrain. The 4th edition is divided into six major parts:

1. The Realm of Biochemistry (Water, pH, buffers, thermodynamics)
2. Molecular Architecture of Living Matter (Amino acids, proteins, carbohydrates, lipids, nucleic acids)
3. Dynamics of Life (Enzymes, kinetics, mechanisms, regulation)
4. Metabolism (Glycolysis, TCA cycle, oxidative phosphorylation, photosynthesis, lipid & nitrogen metabolism)
5. Genetic Information (DNA replication, repair, transcription, translation, genetic code)
6. Special Topics (Immunology, molecular motors, signal transduction)

Each chapter contains 20–40 problems. Quantitative problems (calculating Keq, delta G, Vmax, or sedimentation coefficients) are mixed with conceptual questions (drawing mechanisms of chymotrypsin or explaining allostery).

A "Biochemistry Mathews 4th Edition solution" typically refers to worked answers for these problems. No official solutions manual was ever sold separately to the general public without an instructor’s verification—hence the high demand among self-learners and study groups.
