Question

During the chemiosmotic synthesis of ATP in photosynthesis, ______.  

पर्याय

• the protons accumulate m the intermembrane space of the chloroplast. 

• the proton gradient is not required.

• the protons accumulate m the intermembrane space of mitochondrion.

• the protons accumulate within the lumen of the thylakoids.

Answer 1

During the chemiosmotic synthesis of ATP in photosynthesis, the protons accumulate within the lumen of the thylakoids

Explanation:

Energy is released between Cyt-b₆ and Cyt-f during non-cyclic photophosphorylation in photosynthesis, and this energy is used to build a proton gradient across the thylakoid membrane. As a result, more protons gather in the thylakoid lumen. As a result, there is a large concentration of proton in the thylakoid lumen.
