What is Photosynthesis Reaction?

Photosynthesis Reaction

It is the most important chemical reaction for life on the earth. What do pizza, campfires, automobiles dolphins and glaciers have common between them? They all rely on photosynthesis reaction. Some rely on many ways.

Similarly, we also consider that photosynthesis is the most important chemical reaction for life on the planet earth. Let us delve into the working of this process of photosynthesis reaction. And also find out why we are so indebted to it.

Process of Photosynthesis Reaction

Photosynthesis reaction involves a series of chemical reactions. Each of which converts one substance to the other substance. When taking this reaction as a whole we can summarize it in a single symbolic representation. As in the chemical reaction mentioned below.

6CO2 + 6H2O + light C6H12O6 + 6O2

photosynthesis reaction

We can substitute words for chemical symbols. Then the equation appears as follows:

Carbon Dioxide + Water + Light Energy Glucose + Oxygen Gas

Likewise, the other chemical equations, this equation for photosynthesis process shows that the reactants have a connection through plus signs. Moreover, on the left and products, also have a connection by the plus signs, on the right. Further, an arrow that that indicates the process or the chemical range leads from the reactants to the products.

And conditions are necessary for the chemical reaction are written over the top of the arrow. Similarly, the same kinds of atoms and the number of atoms are present on both of the sides of the equation. But, the types of compounds they form a change.

Application of Photosynthesis Reaction

We use chemical reactions every time we are cooking or baking. After that, we add the ingredients together (the reactants), place them in a suitable specific condition (often heat), and then enjoy the result that it gives (the products). The photosynthesis reaction is shown below:

6CO2 + 6H2O + Light C6H12O6 + 6O2

The above equation shows that the ingredients for the photosynthesis process are carbon dioxide, light energy, and water. Algae, plants and photosynthetic bacteria take in light through the sun, water molecules from their environment and carbon dioxide from the air and combine these reactants to produce the food i.e. glucose.

Of course, light, water and carbon dioxide mix up in the air even without the plants. However, they do not change chemically for making food without very specific necessary conditions. Similarly, these are found only in the cells of photosynthetic organisms. The necessary situation for this includes:

Enzymes – proteins that speed up the chemical reactions.

Chlorophyll – a pigment within the cells of the plants that absorbs the light.

Chloroplasts – organelles whose membranes embed accessory pigments, chlorophyll, and enzymes in patterns that maximize the photosynthesis process.

Within cells of the plants or algal cells, chloroplasts organize enzymes, accessory pigment molecules and chlorophyll and that are necessary for the photosynthesis process.

Efficiency of Photosynthesis

Further, the photosynthetic efficiency is the fraction responsible for converting into chemical energy in the duration of the photosynthesis method. Moreover, it occurs in plants and algae. Photosynthesis can be described by the simple chemical reaction given below:

6H2O + 6CO2 + energy → C6H12O6 + 6O2

Algae and Other Monocellular Organisms

From a study of 2010 by the University of Maryland. Moreover, photosynthesizing Cyanobacteria have been shown to be a particular species in the global carbon cycle. Accounting for 20-30% of Earth’s photosynthetic productivity and then converts the solar energy. Therefore, this results in the formation of biomass-stored chemical energy at the rate of ~450 TW.
