acceptor molecule造句

• Lactoperoxidase catalyzes the hydrogen peroxide ( H 2 O 2 ) oxidation of several acceptor molecules:
• The organyl group on sn-1 of the donor or acceptor molecule can be alkyl, acyl or alk-1-enyl.
• Redox reactions are chemical reactions in which electrons are transferred from a donor molecule to an acceptor molecule.
• These enzymes catalyse the transfer of sugar moieties from activated donor molecules to specific acceptor molecules, forming glycosidic bonds.
• When combined with the free radical-forming TCNQ as an acceptor molecule, it can mimic the mechanism of metallic magnets.
• Photons absorbed in the spectrum transfer energy to the reaction center and excite the electron to an electron acceptor molecule.
• Previous experiments to determine conductivity have involved doping the DNA with electron donor and acceptor molecules, and have been inconclusive.
• This process is called resonance energy transfer, and the rate depends strongly on the distance between the energy donor and energy acceptor molecules.
• In the second reaction, occurring in the CT domain of an adjacent monomer, carbon dioxide is transferred to the acceptor molecule, pyruvate, to form oxaloacetate.
• The electron transport chain consists of a spatially separated series of redox reactions in which electrons are transferred from a donor molecule to an acceptor molecule.
• In organic photovoltaics, effective fields break up excitons by causing the electron to fall from the conduction band of the absorber to the conduction band of the acceptor molecule.
• The electron accepting power of an acceptor molecule is measured by its electron affinity which is the energy released when filling the lowest unoccupied molecular orbital ( LUMO ).
• This family includes glucosyltransferases or sucrose 6-glycosyl transferases ( GTF-S ) ( CAZY GH _ 70 ) which catalyse the transfer of D-glucopyramnosyl units from sucrose onto acceptor molecules.
• The highly excited electrons are transferred to the acceptor molecule, but this time are passed on to an enzyme called Ferredoxin-NADP + reductase which uses them to catalyse the reaction ( as shown ):
• The possibility of the formation of a complex between sensitizer and acceptor molecules was excluded by the additivity of the absorption spectra and the different dependence on concentration to be expected in this case.
• That's where a key step in photosynthesis happens : The energy gathered by LH1 and LH2 pulls an electron out of still another chlorophyll molecule and attaches it to an " acceptor molecule ."
• In chemistry, the class of electron donors that donate not just one, but a set of two paired electrons that form a covalent bond with an electron acceptor molecule, is known as a Lewis base.
• For photosystem II, when either of the two chlorophyll " a " molecules at the reaction center absorb energy, an electron is excited and transferred to an electron acceptor molecule, pheophytin, leaving the chlorophyll " a " in an oxidized state.
• When the electron reaches photosystem I, it fills the electron deficit of the reaction-center chlorophyll of photosystem I . The deficit is due to photo-excitation of electrons that are again trapped in an electron acceptor molecule, this time that of photosystem I.
• The cyclic reaction takes place only at photosystem I . Once the electron is displaced from the photosystem, the electron is passed down the electron acceptor molecules and returns to photosystem I, from where it was emitted, hence the name " cyclic reaction ".
