Photolysis refers to any chemical reaction in which a compound is broken down by light.
 Photolysis in photosynthesis
Photolysis is a part of the light-dependent reactions of photosynthesis. The general reaction of photosynthetic photolysis can be given as:
H2A + 2 photons (light) 2e- + 2H+ + A ...

Photolysis of water, with liberation of molecular oxygen, and photophosphorylation of ADP, with production of ATP and NADPH, are the processes that occur during the photochemical stage of photosynthesis.
Meanwhile the photosystem's stolen electron is replenished by ~, or the splitting of H2O to form H+and O2 (note: the H+ is kept in side the thylakoid membrane). The O2 resulting is the source of all oxygen in our atmosphere
The electron travels down the electron transport system (ETS).
6. In what part of photosynthesis would the tracer carbon-14 be used to study the path of carbon through the chemical reactions?
a) the absorption of light by chlorophyll
b) the dark reactions
d) the light reactions ...
In this study, we applied advanced biophysical techniques, such as patch clamp、membrane capacitance measurement、microfluoremetric technique、flash ~、TIRFM、and so on.
ATP and hydrogen derived from ~ of water are used to fix carbon dioxide to make organic molecules.
3.8.7 Explain that the rate of photosynthesis can be measured directly by the production of oxygen or the uptake of carbon dioxide, or indirectly by an increase in biomass.
a) (i) oxygen produced during ~/using light energy; from breakdown of water
(ii) DCPIP accepted hydrogen/protons/H+

Hill reaction The splitting of a molecule of water during the light reactions of photosynthesis; the ~ of water.
hilum Scar on a seed indicating where it was attached to the ovary.
hindbrain Includes the medulla oblongata, cerebellum, and pons.
These electrons and hydrogen ions come from the ~ of H2O into O2 and electrons e- and H+. So, as we discussed earlier, a plant uses water and carbon dioxide and sunlight to make sugars and oxygen. (Those sugars get modified to form the other required middle-sized biomolecules.) ...
