What must be the chemical property of the electron acceptor
What must be the chemical property of the electron acceptor molecule that is reduced by electron transfer when chlorophyll loses an electron as a result of photooxidation? Choose the TWO best answers.
Question 8 options:
The acceptor molecule must have a higher reduction potential than chlorophyll (more positive).
The metal ion in both the acceptor molecule and chlorophyll must both contain manganese.
The ring structures of the acceptor molecule and chlorophyll cannot both contain nitrogen.
The acceptor molecule must have a higher reduction potential than chlorophyll (less positive).
The acceptor molecule must have a lower reduction potential than chlorophyll (more positive).
The acceptor molecule must be in close proximity and be oriented correctly to facilitate the electron transfer reaction.
There are not two correct answers.

Solution
Since the reduction potential directly impacts on the reduction of the electron acceptor molecule, the higher the reduction potential, greater its affinity towards its reduction.
So, one of the most chemical property of the electron acceptor molecule that is reduced by electron transfer when chlorophyll loses an electron as a result of photooxidation, is its higher reduction potential than chlorophyll (more positive).
and there are not two correct answers.
