Read the following Assertion and Reason and choose the correct option. Assertion: Biosynthetic phase of photosynthesis is not dependent on products of light reaction Reason: When light becomes available the process stops

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

D. Both Assertion and Reason are false

Step-by-step solution

Biosynthetic process does not directly depend on the presence of light but is dependent on the products of the light reaction, i.e., ATP and NADPH, besides CO2 and H2O. Immediately after light becomes unavailable, the biosynthetic process continues for some time, and then stops. If then, light is made available, the synthesis starts again.
