Read the following Assertion and Reason and choose the correct option. Assertion: A proton gradient across the thylakoid membrane as well as a measurable decrease in pH in the lumen is observed Reason: The NADP reductase enzyme is located on the thylakoid side of the membrane

Options

  1. ABoth Assertion and Reason are true and Reason is correct explanation of Assertion
  2. BBoth Assertion and Reason are true but Reason is not the correct explanation of Assertion
  3. CAssertion is true but the Reason is false
  4. DBoth Assertion and Reason are false

Correct answer

C. Assertion is true but the Reason is false

Step-by-step solution

Within the chloroplast, protons in the stroma decrease in number, while in the lumen there is accumulation of protons. This creates a proton gradient across the thylakoid membrane as well as a measurable decrease in pH in the lumen.
