Question
# Binding Change Mechanism of ATP Synthase

**Question:**  
Which is the correct link between conformation of the beta-subunit of the F₁ component of ATP synthase and ADP + Pᵢ or ATP?

**Diagram Explanation:**  
The diagram describes the binding change mechanism within ATP synthase, focusing on the conformation changes of the beta-subunit. This is crucial for the synthesis of ATP from ADP and inorganic phosphate (Pᵢ).

- **First Conformation:**  
  - Labeled as "open," depicted with ADP + Pᵢ loosely bound.
  
- **Second Conformation:**  
  - Transitions to a state labeled "tight binding," indicating the catalysis of ADP + Pᵢ into ATP.  
  
- **Third Conformation:**  
  - Alters to release ATP, resetting the binding site for another cycle.

This cycle continuously repeats, facilitating ATP production.

**Multiple Choice Options:**

- ☐ loose => binding ADP + Pᵢ
- ☐ open => catalyzes ADP + Pᵢ into ATP
- ☐ tight => releases ATP
- ☐ open => releases ADP + Pᵢ

This mechanism illustrates the efficiency of ATP synthase in energy production, essential for cellular processes.
