We can describe Photosynthesis basically as the process through which plants are using the sun’s energy for the production of food for themselves.
But here we will take a closer look at a more complex and profound definition of what we call Photosynthesis.
Next lesson: Top Four Kingdoms
The video transcript is for your convenience. We are taking a look at what the process or reaction actually is looking like that makes this happen. The process of Photosynthesis is chlorophyll that contains autotrophs that use sunlight and the sun’s energy to convert water and carbon dioxide into Carbohydrates (Glucose).
So by saying autotrophs, we can also say primary producer. So basically it is a plant that does not consume anything for producing energy and food for itself. All right. This is what this reaction actually is looking like. We are having light plus 6 moles of carbon dioxide and also water to produce our carbohydrate.
So that’s what we go for.
This is also producing oxygen but here, oxygen is seen as a waste product for the reason that this reaction’s goal is NOT the creation of oxygen. The goal is to create carbohydrates.
The photosynthesis process is involving two stages: the light reaction & the dark reaction.
In the light reaction, photons (from light) are providing the energy for splitting water molecules and the released electrons will be boosted into a high energy state and they will generate the reducing equivalence as well as the energy-carrying ATP molecule.
Then, we have also the dark reaction. This, we can refer to as the Calvin Benson cycle as well.
Here, carbon dioxide in the atmosphere will be captured and then converted by a reducing equivalence and the ATP molecule into, firstly, 3 carbon sugars, and later, it will be converting into 6 carbon-sugar phosphates and later again, into cellulose and sucrose starch.
