∙ 9y agoThe electron donor in oxygenic photosynthesis is water. The electron acceptor in oxygenic photosynthesis is CO2. Chlorophyll is converted from a weak electron donor to a strong electron donor.

∙ 15y agoIn the light reaction, e- are donated by H20 in photosystem II which is located in the thylakoid membrane. In photosystem one, the NADP+ is reduced to NADPH with the electrons from PS II.
Fun fact. Hydrogens from H20 also create a proton gradiant between stroma and thylakoid membrane driving CF1CF0 ATP synthase.

Where do electrons get their energy from light reactions?
From the photons is solar energy.
Where electrons get their energy in the light reactions?
.From photons in solar energy
The light reactions of photosynthesis generate high-energy electrons which end up in The light reactions also produce and?
NADPH
What does energy come from to make nadaph in light reactions?
From electrons in photosystem I that are excited to a higher energy state by photons of light. Then NADP + is reduced to become NADPH
What reactions convert light energy to chemical energy?
The light dependent reactions take in the light energy and convert that to chemical energy, but it is in the Calvin cycle (light independent reactions) where the chemical energy is stored in a complex sugar.
Where do electrons get their energy from light reactions?
From the photons is solar energy.

The light reactions of photosynthesis generate high-energy electrons which end up in The light reactions also produce and?
NADPH
What is the high energy compound that is the result of light dependent reactions?
ATP is produced from the light reactions, which is then coupled with the light independent reactions. NADPH is also produced, but its job is to carry electrons which eventually make ATP.
How do the light reactions and dark reactions work together?
The light reactions provide energy carriers for the dark reactions.
What is the role of ATP in light-dependent reaction?
ATP is generated in the light independent reactions and is then used in the dark reactions to synthesize carbohydrates. ATP plays the role of the product of phosphorylation of ADP.

Why is light an important factor in all chemical reactions?
Light usually provides enough energy for exchange of electrons and carry out the chemical reaction.
Why are light reactions required for the photosynthetic process?
Chloroplasts convert light energy into chemical energy. The energy of light captured by pigment molecules, called chlorophylls, in chloroplasts is used to generate high-energy electrons with great reducing potential.
What is reduced by electrons in light reactions?
NADP+
Light-dependent reactions of photosynthesis?
The light-dependent reactions, or light reactions, are the first stage of photosynthesis. In this process light energy is converted into chemical energy, in the form of the energy-carriers ATP and NADPH. In the light-independent reactions, the formed NADPH and ATP drive the reduction of CO2 to more useful organic compounds, such as glucose.
