Question

Particles of thylakoid membranes involved in ATP synthesis are called

• A. Quantasomes
• B. $C{F}_0-C{F}_1$
• C. Photosystems
• D. Pyrenoids

Answer 1

Answer: (B)

$C{F}_0-C{F}_1$

• The particles of thylakoid membrane responsible for ATP synthesis is a CF${}_1$ -CF${}_O$-ATP synthase.
• It is embedded in the thylakoid membrane where the CF${}_1$-part is attached to the stroma.
• Therefore, ATP synthesis occurs on the stromal side of the thylakoid where the ATP molecules are required for carrying out the light-independent reactions of photosynthesis.
  
• So, the correct answer is 'CF${}_0$−CF${}_1$'.
