They are replaced by electrons donated from water molecules which were split by enzymes in the thylakoids inside chloroplasts.
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.
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.
Energy is obtained from ATP in biological systems through a process called hydrolysis. This involves breaking down ATP molecules into ADP and inorganic phosphate, releasing energy that can be used for cellular processes.
Carbon skeletons for cellular respiration can be obtained from glucose, fatty acids, and amino acids. These molecules are broken down in different metabolic pathways to generate energy in the form of ATP.
Animal cells do not obtain their energy directly from chlorophyll. However, chlorophyll is vital for the survival of animals. Chlorophyll is the pigment contained in chloroplasts, which are the organelles in plants responsible for photosynthesis. Photosynthesis involves converting energy into a form that animals can use (glucose). This glucose is then broken down in the animal cell for energy. Therefore chlorophyll is indirectly responsible for producing the energy for animal cells.
chlorophyll; water
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+.
Mainly (99%) from chlorophyll.
The graph suggests that chlorophyll absorbs light most efficiently in the blue and red regions of the spectrum. This is because chlorophyll molecules absorb light most strongly in these regions, which corresponds to the wavelengths most useful for photosynthesis.
They are obtained from water. Photolysis of water release Electrons
Because electrons are obtained from water. Process is called photolysis
After a chemical change new molecules are obtained.
New elements can by obtained only by nuclear reactions.New molecules can be obtained by chemical reactions.
From, Ultimately, The Sun.
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.
After a chemical change new molecules are obtained.
The number of water molecules obtained is 120,44281714.10e23.
