Read the following statements and choose the following option: 1. Dark reactions are solely water controlled 2. The C4 plants respond to lower temperatures 3. In chemiosmosis within the chloroplast, protons in the stroma decrease in number, while in the lumen there is accumulation of protons. 4. The ATP synthase enzyme consists of two parts: one called the CF0 and the other is CF1.

Options

  1. AOnly 3 is correct
  2. BOnly 1 is correct
  3. CBoth 1 and 4 are correct
  4. DBoth 1 and 2 is incorrect

Correct answer

D. Both 1 and 2 is incorrect

Step-by-step solution

The dark reactions being enzymatic are temperature controlled. Though the light reactions are also temperature sensitive they are affected to a much lesser extent.
