Which of the following events are associated with chemiosmosis in chloroplasts? Which of the following events are associated with chemiosmosis in chloroplasts? The pH of the stroma decreases and ATP is hydrolyzed. The pH of the cytoplasm outside the chloroplast decreases and ATP is synthesized. The pH of the thylakoid space increases and ATP is synthesized. The pH of the stroma increases and ATP is synthesized.

Solutions

Expert Solution

The event associated with chemiosmosis in chloroplast is T

The pH of the thylakoid space increases and ATP is synthesized.

Steps involved in this process

1. The protons form the stroma are pumped into the intratylakoid sac.

2. A pH gradient generates between the inside and the outside of the intrathylakoid sac. Inside high H⁺ concentration (lower pH)

3. pH gradient helps formation of free energy.

4. H⁺ crosses back across the membrane through the CF complex.

5. CF contains ATPase which produces ATP fromn ADP and P.

6. 3 H⁺ pass through the CF to make 1 ATP,

7. The source of H⁺ and electrons is water.

8. NADP is the final electron acceptor producing NADPH

Which of the following statements about chloroplasts is true? Group of answer choices The stacks of interconnected sacs within the chloroplast are known as stroma; this is where the light-collecting for photosynthesis occurs. The stacks of interconnected sacs within the chloroplast are known as thylakoids; the light-collecting for photosynthesis occurs here. Chloroplasts are found in eukaryotic cells, therefore they contain linear DNA. The DNA of the chloroplast is found within the thylakoid sacs. The chloroplast has one single membrane layer...
