Which photosystem is used first in photosynthesis?

Photosystem 2 happens in photosynthesis before photosystem 1. However they are numbered in order of how they were discovered. Photosystem 1 was discovered before photosystem 2. In photosynthesis the order of them is 2 then 1. meaning that photosystem 1 was discovered 1st but photosystem 2 happens 1st in photosynthesis


What happens to electrons when pigments in photosystem II absorbs light?

they move through an electron transport chain to photosystem 1


What happens to electrons when pigments in photosystem absorb lights?

Photosystem's electron travel through the electron transport chain(etc) where ATP is produced and then back to the photosystem. In non-cyclic photophosphorylation, Photosystem II electron then is absorbed by photosystem I, photosystem I electron used to form NADPH and photosystem II gets its electron from photolysis of water. For you unfortunate children using Novanet: They move through an electron transport chain to photosystem 1.


What happens after photosynthesis?

- ATP is the end result after Photosystem II. - NADPH is the end result for Photosystem I. They are sources of energy & they use sugars for energy storage/transport.


What happens when an excited electron is passed to an electron acceptor in a photosystem?

When an excited electron is passed to an electron acceptor in a photosystem, energy in sunlight is transformed to chemical energy.


What protein complex absorbs in energy that used to produce NADPH?
