Question

$M{g}^{2+}$ and $C{l}^{-}$ are required during transfer of electron from

• A. $O{H}^{-}$ to $Chlorophyll-a_{683}$
• B. $O{H}^{-}$ to $P_{700}$
• C. $FD$ to $FRS$
• D. $Cytochrome-b$ to $cytochrome-f$

Answer 1

The correct option is A $O{H}^{-}$ to $Chlorophyll-a_{683}$

• Magnesium and chlorine form an ionic bond. Covalent bonds are formed when two or more atoms share electrons between them.
• Ionic bonds are when atoms gain or lose an electron to become charged species that share an electrostatics interaction called an ionic bond.

So, the correct option is 'OH- to chlorophyll -a683'
