They are replaced by electrons donated from water molecules which were split by enzymes in the thylakoids inside chloroplasts.

Photolysis splits H2O to provide an electron for chlorophyll in the reaction center and to provide hydrogen ions to drive ATP production. This reaction is in the PSII noncyclic photosynthetic reaction only.

What pigment traps the energy for photosynthesis?
There is a wide range of pigments that are used for photosynthesis. However, chlorophyll is responsible for using obtained light energy to excite electrons to move through the transport chain. Many pigments are only capable of transferring energy to chlorophyll, but they are important because they increase the spectrum of the frequencies of light of which the organism can use to photosynthesize. These pigments are called accessory pigments. For a more detailed explanation of these pigments, view the attached link below.
Is the beginning of photosynthesis pigments in photosystem absorb light?
Yes, that is correct. The light energy excites electrons in photosystems and these electrons enter the electron transport chain to make ATP. These electrons eventually end up in NADPH and photosystems are replenished with electrons obtained from splitting water.
Which group of organic molecules makes up enzymes?
Proteins. Answer obtained from biology class.
Is energy needed for photosynthesis take place?
Yes energy is needed for photosynthesis and plants use light energy which they get from solar radiation.
How many ATP (net) are made in the glycolysis part of cellular respiration?
Glycolysis is a 10 step enzymatically catalyzed reaction which splits up a glucose molecule into two molecules of pyruvate. The process of glycolysis can occur in absence of oxygen. A net yield of 2 ATP is obtained at the end of gylcolysis for every molecule of glucose oxidized.
Electrons passed to nadph during noncyclic pathway are obtained from but ultimately from?
chlorophyll; water
The electrons that are passed to NADPH during noncyclic photophosphorylation were obtained from?
The electrons that are passed to NADPH during noncyclic photophosphorylation were obtained from water. The ultimate electron and hydrogen acceptor in the noncyclic pathway is NADPH+.
How is solar energy obtained from nature?
Mainly (99%) from chlorophyll.
Where is the glucose needed for processes obtained from?
From, Ultimately, The Sun.
Where do plants get their replacement electrons?
They are obtained from water. Photolysis of water release Electrons
What are the characteristic of a covalent?
In covalent bonds, no electrons are obtained or released. They share the bonding electrons.
Why doesn't the photo-system run out of electrons?
Because electrons are obtained from water. Process is called photolysis
What does chemical produce?
After a chemical change new molecules are obtained.
Can new elements be produced in a chemical reaction can new molecules be produced through a chemical reaction?
New elements can by obtained only by nuclear reactions.New molecules can be obtained by chemical reactions.
What does not require energy obtained from pre-formed organic molecules?
Autotrophs
What does chemical change produce?
After a chemical change new molecules are obtained.
If 5.0 mols of C3H8 react how many molecules of water are formed and gt?
The number of water molecules obtained is 120,44281714.10e23.
