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.

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. The ring structures of the acceptor molecule and chlorophyll cannot both contain nitrogen. The acceptor molecule must have a lower reduction potential than chlorophyll (more positive) 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 acceptor molecule must be in close proximity and be oriented correctly to facilitate the electron transfer reaction. There are not two correct answers. The acceptor molecule must have a higher reduction potential than chlorophyll (less positive).

Solution

The first answer would be:-

That the molecule must have a higher reduction potential than chlorophyll (more positive) .

This is because as the reduction potential increases, the tendency to get reduced increases. It also becomes more positive as it increases.

The second best answer would be:

The acceptor molecule must be in close proximity and be oriented correctly to facilitate the electron transfer reaction.

This is because the electron transfer could not be done if the orientation and proximity of the molecules do not match.

Option 3 and 5 are the best answers.
