Photosynthesis Process
Photosynthesis is a Biochemical Process that occurs in
plants, algae, and some bacteria, Creating the Atmospheric Oxygen and food that
sustain the majority of life on Earth.
The process uses sunlight to convert water and Carbon
Dioxide into Carbohydrates and Oxygen. It works into two stages : The Light
Dependent Reaction and The light Independent Reaction. In Senior High School,
generally known as Aerob Reaction and Anaerob Reaction.
The First stage is The Light Dependent Reaction. In this
first step of Photoshnythesis, sunlight enters the first Photosystem and
energizes the Chlorophyll.
The excited Chlorophyll splits water into Oxygen and
Hydrogen. Meanwhile, the chlorophyll feeds electrons into a complex sequence of
nearby molecules called the electron transport chain.
The freed Oxygen escapes into Athmosphere, While the freed
Hydrogen is used later in The light Independent Reaction. As electrons move along the electron transport chain, their
energy make the molecule ATP, which is used by all known forms of life to fuel
their cellular functions. The electrons enter a second Photo system, get full
energized by sunlight, and move along another electron transport chain to
construct a molecule called NADP. The second stage is The Light Independent Reaction. NADP
combines with Hydrogen, which was freed earlier in The Light Dependent
Reaction, to produce NADPH.
NADPH, ATP, and Choloroplast Enzyme called Rubisco, work
together to create sugars and other Carbohydrates from Carbon Dioxide and Water
in a Process called The Calvin Benson Cycle. It is a very complex reaction that
Fixes Carbon from the Athmosphere forming The Foundation of Earth’s major food
chains plants directly use sugar as their food, and many other organisms eat
plants to gain their stored energy.
We can also conclude that Photosynthesis is how plants use
light and water to make sugar and It is created in the green parts of a plant
and every animal on earth depends on it. So, Without plants we would have no
food to eat or oxygen to breath
