Read the following Assertion and Reason and choose the correct option. Assertion: Electrons are not used up in electron transport chain Reason: In photosystem II the reaction centre chlorophyll a absorbs 680 nm wavelength of red light

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

B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion

Step-by-step solution

The electrons are not used up as they pass through the electron transport chain, but are passed on to the pigments of photosystem PS I.
