Explanation / Answer

8 - The correct answer is option C that is photosystem.

There are two types of photosystem, PS-I and PS-II both having different pigments and molecules that absorb different wavelengths of light.

9) The correct answer is option C that is oxidized as FADH2 to FAD and NADH to NAD loses the hydrogen and losing of hydrogen is known as reduction.

10- The correct answer is option E that is sister chromatids.

11- The correct answer is option D that is photo respiration.
