Question

question 42 from which photosystem(s) are excited electrons transferred to an electron transport system? neither photosystem i or photosystem ii photosystem i both photosystem i and photosystem ii photosystem ii

Explanation:

In photosynthesis, excited electrons from both photosystem I and photosystem II are transferred to an electron - transport system. Photosystem II initiates the electron flow by exciting electrons which are then passed through a series of electron carriers, and photosystem I also contributes excited electrons to the electron - transport chain.

Answer:

both photosystem I and photosystem II
