Read the following Assertion and Reason and choose the correct option. Assertion: ATP synthesis in photosynthesis is linked to development of a proton gradient across a membrane Reason: Cyclic photophosphorylation does not occur when only light of wavelengths beyond 680 nm are available for excitation

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

In photosynthesis , ATP synthesis is linked to development of a proton gradient across a membrane. These are the membranes of thylakoid. Here the proton accumulation is towards the inside of the membrane, i.e., in the lumen.
