Photosynthesis

The light-dependent reaction also creates NADPH in Photosystem I. When the electrons from the electron transport chain reaches photosystem I, they regain energy from a photon captured from the chlorophyll.
The electron's energy causes NADP+ to create NADPH and a hydrogen ion from H+. The energy is then used to make sugar molecules.
In light-independent reactions, it uses the chemical energy from the light-dependent reactions to make sugar molecules from CO2
Light is a major part of this reaction since it causes enzymes to activate. This reaction also uses energy carriers to store energy for a while (the energy isn't saved forever; it has to be used at a point).

In the cycle, sunlight is converted and packaged into NADPH & ATP, these 2 things are used as fuel/energy to make carbohydrate molecules. These molecules will have carbon atoms with them too.
-
A reduction reaction occurred (electrons were gained by an atom/molecule). After the reaction ,ADP & NAD+ were made, however, were sent back to the light-dependent reactions to be re-energized.

A process where plants, bacteria, algae take in sunlight and convert it into chemical energy to make carbohydrate molecules. These 3 things are autotrophs (self feeders) since they can create their own food
It requires sunlight, carbon dioxide (CO2) and water (H2O). After the process is completed, oxygen is released and glyceraldehyde-3-phosphate (GA3P) is made. The carbohydrate molecules converts in sugar, glucose + more sugar molecules.
In plants, photosynthesis occurs in the middle layer, mesophyll, in the leaves. CO2 and oxygen are exchanged in small openings of the stomata. The stomata regulates the gas exchanges and the water balance.
There is 2 stages that the process breaks up into that are connected to one another: Light-Dependent Reactions and Light-Independent Reactions
Light Dependent Reaction: Sunlight energy is collected by the chlorophyll. Then the energy gets converted into stored chemical energy
Light dependent reaction starts when pigment molecules and proteins are grouped (named as a photosystem) together. The photosystem (2 of them) is in the membrane of thylakoids which are in chloroplasts (organelle in cells). The pigment molecules' role are taking in a photon of light energy (small amount) at a time.
Photons of light energy goes to the pigment molecule (chlorophyll). 1 photon makes 1 electron "excited"/energetic which causes it to travel to other pigment molecule until it reaches the reaction center of the chlorophyll. Then from the reaction center, the electron becomes free and attaches to a primary electron acceptor. The reaction center is there to send electrons to the acceptor.
That's not the only thing that occurs in the reaction center. When an electron reaches the center, a molecule of water splits. The splitting causes the electron to create oxygen (O2) and hydrogen ions (H+) in the thylakoid space. However, for every split of a water molecule, 2 electrons can be replaced in the center again. In other words, there are no gaining of electrons; neutral.
