MCQ
In photosynthesis, what does occur in $PS-II$?
  • A
    It takes longer wavelength of light and $e^{-i, 6}$ from $H _{2} O$
  • It takes shorter wavelength of light and $e^{-i i}$ from $H _{2} O$
  • C
    It takes longer wavelength of light and $e^{-i t}$ from $NADP$
  • D
    It takes shorter wavelength of light and $e^{-i i}$ from $NADP$

Answer

Correct option: B.
It takes shorter wavelength of light and $e^{-i i}$ from $H _{2} O$
b
$PS-II$ absorbs maximum $680 \;nm$ wavelength of light, thus reaction centreis $P_{\infty 0} \cdot P_{t B 0}$ $(PS-II)$ extracts an electron from water, returning to its unexcited state because hydrolysis of water occurs in $PS-II$. Oxygen evolved in $PS-II$ comes from water:
