Question

As electrons move through the electron transport chain, they are passed from:

1) a carrier molecule of lower electron affinity to a carrier molecule of higher electron affinity.
2) a carrier molecule of higher electron affinity to a carrier molecule of lower electron affinity.

Answer 1

Electrons are passed from a carrier molecule of higher electron affinity to a carrier molecule of lower electron affinity during the electron transport chain.

Step-by-step explanation:

During the electron transport chain, electrons are passed from a carrier molecule of higher electron affinity to a carrier molecule of lower electron affinity.
