In photosynthesis redox reactions ultimately transfer electrons from where?

§Photosynthesis, like respiration, is a redox (oxidation-reduction) process
-Water molecules are split apart by oxidation, which means that they lose electrons along with hydrogen ions (H+)
-Then CO2 is reduced to sugar as electrons and hydrogen ions are added to it
This means that the electrons are moved from a water molecule to a carbon dioxide molecule. H2O >> CO2

What transfers energy from glucose to other molecules during redox reactions in?
Electrons transfer energy from glucose to other molecules during redox reactions in cells.
What does FAD turn into?
Generally FAD is reduced to FADH2 by accepting two electrons and two protons which it brings to the electron transfer chain where the protons and electrons are ultimately used to produce ATP.
List and describe the four processes in the oxidation of glucose to CO2 and water?
One is transfer of energy in chlorophyll. The other is transfer of electrons, which happen in photochemical reactions. Another is transport chain for electrons and synthesis of ATP. The final process concerns carbon fixation and release of products.
Where in the chloroplast do the light dependent reactions take place?
They occur in the thylakoid membranes of the chloroplasts in plant cells. They are light dependent in that they need the energy given off by the sun to "excite" the electrons in order to move down the electron transfer chain, which ultimately prepares them to be used by NADP+ to form NADPH to assist in the light independent cycle. (Calvin Benson Cycle)
How many times are electrons energized during photosynthesis?
The thylakoid membrane contains 2 photosytems, known as Photosystem I and Photosystem II. Together, they function to absorb light and transfer energy to electrons.
What reaction involves the transfer of electrons?
A REDOX reaction involves transfer of electrons.
What kinds of reactions are redox reactions?
Electron transfer reactions. reactions involving losing and gaining electrons
Which phrase best describes the electron transport chain in photosynthesis?
Yes. Photosynthesis involves the transfer of electrons. Photosynthesis causes a chemical change. All chemical changes involve either the transfer of electrons or a change in the configuration of electrons. No other way exists to make a chemical change.
How does electrons movements affect making new substances?
Chemical reactions are based on electrons transfer or sharing.
What transfers energy from glucose to other molecules during redox reactions in?
Electrons transfer energy from glucose to other molecules during redox reactions in cells.
What happens to electrons in a redox reaction?
Electrons may be transferred from one particle to another.
What transfer energy from glucose to other molecule during redox reactions in cells?
electrons ur welcome
What transfer energy from glucose to other molecules during redox the reactions in cells?
electrons ur welcome
What are the negatively charged particles within an atom that are involved in chemical reactions?
Those would be the electrons (found "orbiting" the atomic nucleus). Chemical reactions normally involve transfer or sharing of the "outer shell" electrons.
What is the transfer of electrons from one molecule to another?
Oxidation-reduction reactions
Why is cellular process coupled?
The transfer of electrons (source of energy) go from one reaction in which loosing electrons (oxidation) is favoured to one where the gaining of electrons (reduction) is favoured, that's why such reactions are coupled.
What is true about oxidation-reduction reactions?
They involve either transfer of electrons, or a change in the oxidation state of some atoms involved.
