🦁

Remember the mnemonic "G-HAT" (Gibbs = H minus T times S) to recall the free energy equation.

📖 Chapter 2: ATP and Enzyme Function

What this chapter covers:

🔑 Essential Concepts & Formulas

🛠️ Problem Types

Type A: Calculating Energy from ATP Hydrolysis

Type B: Identifying Enzyme Inhibition Type

🧮 Solved Example

Problem:

Given:

Answer:

⚠️

❌ Mistake 1: Confusing cofactors and coenzymes ✅ How to avoid:

❌ Mistake 2: Thinking enzymes change ΔG ✅ How to avoid:

🦁

Remember "ACE" - Active site, Competitive inhibitor, Enzyme. This helps remember competitive inhibitors bind to the active site.

📖 Chapter 3: Cellular Respiration

What this chapter covers:

🔑 Essential Concepts & Formulas

🛠️ Problem Types

Type A: Calculating ATP Yield

Type B: Identifying Redox Reactions

🧮 Solved Example

Problem:

Given:

Answer:

⚠️

❌ Mistake 1: Forgetting the location of each stage ✅ How to avoid:

❌ Mistake 2: Confusing ATP production in different stages ✅ How to avoid:

🦁

Remember "ETC" - Electron Transport Chain. This is key to oxidative phosphorylation and produces the most ATP.

📖 Chapter 4: Regulation of Respiration

What this chapter covers:

🔑 Essential Concepts & Formulas

🛠️ Problem Types

Type A: Predicting Enzyme Activity

Type B: Identifying Regulatory Mechanisms

🧮 Solved Example

Problem:

Given:

Answer:

⚠️

❌ Mistake 1: Confusing activators and inhibitors ✅ How to avoid:

❌ Mistake 2: Ignoring the role of AMP ✅ How to avoid:

🦁

Remember "AMP Up" - AMP signals low energy and "amps up" glycolysis.
