Photosynthesis products are glucose and oxygen and oxygen is reintroduced into the process.
The process of photosynthesis in plants in which the carbon dioxide produced by all living things is absorbed and the oxygen is reintroduced into the atmosphere.
An overview of photosynthesis in plants:
Photosynthesis is the process used by plants, algae and some bacteria as they absorb energy from sunlight and convert it into chemical energy.
Here, we classify the general principles of photosynthesis and shed light on how scientists study this natural process to help develop clean fuels and renewable energy sources .
Types of photosynthesis:
There are two types of photosynthesis processes :
2.photosynthesis resulting from hypoxia
The general principles of oxygen photosynthesis and oxygenoxia are very similar, but oxygenic photosynthesis is the most common and has been detected in plants, algae and cyanobacteria.
What happens in this process:
During the oxygen photosynthesis process, light energy transfers electrons from water to carbon dioxide, to produce carbohydrates.
In this transfer, the proportion of carbon dioxide is reduced, and the water becomes “oxidized” or lost electrons, and ultimately, oxygen is produced side by side. With carbohydrates.
The process of photosynthesis of oxygen acts as a stabilizer for respiration by taking in the carbon dioxide produced by all living things, and reintroducing the oxygen back into the atmosphere.
2.Photosynthesis resulting from hypoxia:
On the other hand, photosynthesis resulting from hypoxia uses two electron donors other than water.
And this process usually occurs in bacteria such as purple bacteria and green sulfur bacteria, which are primarily found in various aquatic habitats.
David Baum is Professor of Botany at the University of Wisconsin-Madison:
“The process of photosynthesis does not produce oxygen, hence the name,” says David Baum, professor of botany at the University of Wisconsin-Madison.
What is produced depends on an electron donor. For example, many bacteria use hydrogen sulfide, “the gas that smells like rotten eggs,” and they produce Solid sulfur as a by-product. ”
Although both types of photosynthesis are complex, and manifold, the overall process can be precisely summarized as a chemical equation.
The equation for oxygenic photosynthesis is written as:
6CO 2 + 12H 2 O + Light Energy → C 6 H12O 6 + 6O 2 + 6 H 2 O
Here, 6 molecules of carbon dioxide (CO 2 ) combine with 12 molecules of water (H 2 O) using light energy.
The end result is the formation of one carbohydrate molecule (C 6 H 12 O 6 , or glucose) with six molecules each of Breathable oxygen and water.
Likewise, the different reactions of oxidative photosynthesis can be represented as one generalized formula:
CO 2 + 2 H2A + Light Energy → [CH 2 O] + 2 A + H 2 O
The letter (A) in the equation is a variable and H2A represents the potential electron donor. For example, (A) can represent the sulfur in hydrogen sulfide the electron donor (H 2 S).
This was explained by Govindji and John Whitmarsh, plant biologists at The University of Illinois at Urbana-Champaign, in his book “Concepts in Imaginary Biology” on “Photosynthesis
And Photodiagnostics” (1999) also explained that plants need solar energy for photosynthesis to occur.
