MCQ on Chemiosmotic Coupling Mechanism of ATP Synthesis




Chemiosmotic coupling is the mechanism by which ATP is synthesized in mitochondria and chloroplasts. It involves the movement of protons across a membrane, creating a proton gradient. The energy from this gradient drives ATP synthase to convert ADP and inorganic phosphate into ATP. This is an MCQ on Chemiosmotic Coupling Mechanism of ATP Synthesis.

1. 
Who proposed the chemiosmotic hypothesis?

2. 
Where does chemiosmotic coupling occur in eukaryotic cells?

3. 
What is the primary function of chemiosmotic coupling in cellular respiration?

4. 
Which gradient is crucial for ATP synthesis in chemiosmotic coupling?

5. 
Which enzyme synthesizes ATP using the proton gradient in chemiosmotic coupling?

6. 
What is the direction of proton flow through ATP synthase during ATP synthesis?

7. 
Which of the following is NOT involved in chemiosmotic coupling?

8. 
Where is the highest concentration of protons found during chemiosmotic coupling in mitochondria?

9. 
Which process generates the proton gradient used in chemiosmotic coupling?

10. 
What is the role of oxygen in chemiosmotic coupling?
