What else can I help you with?
Where do the excited electrons flowing through photosystem you originally come from?
The excited electrons flowing through photosystem II come from water molecules that are split during the light-dependent reactions of photosynthesis. This process, known as photolysis, releases oxygen as a byproduct and provides electrons to replace those lost when chlorophyll is excited by sunlight.
What happened in photosystem?
Excited electrons are transferred to an electron transport chain.
Electrons are excited in photosystem 1 what do these electrons combine with in order to produce an energy-carrying molecule?
NADP+
Where do electrons get there energy in photosystem 2?
Excited electrons are transferred to an electron transport chain.
What is the waters role in the light reaction of photosynthesis?
Water is split to have its electrons replace the excited electron of chlorophyll, then enters photosystem II.
Where do electrons get there energy from photostem 2?
Electrons in photosystem II get their energy from sunlight. When photons from sunlight are absorbed by the chlorophyll molecules in the photosystem, the energy is transferred to electrons, allowing them to become excited and drive the process of photosynthesis.

Summarize how photosynthetic organisms capture the energy in sunlight?
The light-dependent portion of photosynthesis is carried out by two consecutive photosystems (photosystem I and photosystem II) in the thylakoid membrane of the chloroplasts. The photosystems are driven by the excited chlorophyll molecules.To begin photosynthesis, the chlorophyll molecule in photosystem II is excited by sunlight and the energy produced helps to break down a water molecule (H2O) into ½O2 (with electrons removed) and 2H+. The removed electrons are excited by the light energy. When the electrons prepare to come to their rest state, they go through an oxidative phosphorylation process and produces an ATP molecule.As the electrons are coming to a resting state, they are excited again in photosystem I and raised to a even higher energy state. The excited electrons are then used to produce NADP+ + H+. The highly energetic NADPH molecule is then fed into the Calvin Cycle to conduct carbon fixation.
When sunlight excited electrons in chlorophyll how do the electrons change?
the electrons gain a huge amount of energy

Light excites in photosynthetic pigments?
Light excites two sets of photosynthetic pigments. These are photosystem 1 (PS1) and photosystem 2 (PS2). PS1 is excited by photons at about 700 nanometers, while PS2 is excited at about 680 nanometers.
