Fermentation – Cellular Respiration (Part – III)

By | October 20, 2021

Introduction : Glucose happens to be important and common fuel for many organisms. The process of breaking down of glucose in multistep manner to extract energy present in its C-C bonds (chemical bonds) is called “Cellular Respiration“. Only green plants, Algae and Cyanobacteria have the ability to prepare their own food by the process of… Read More »

Glycolysis – Cellular Respiration (Part II)

By | October 17, 2021

The breakdown of glucose to pyruvic acid in a multi step manner is called as Glycolysis. It takes place in cytoplasm of the cell. It is common pathway to both Anaerobic and Aerobic respiration. The Glycolysis pathway is a very ancient pathway present in majority of organisms from every branch of the bacteria, archaea, and eukaryotes. This… Read More »

Cellular Respiration – Part I

By | October 14, 2021

Earth came into existence some 4.5 billions year ago and based on the fossil evidence from ancient rocks of Greenland, the life on earth dates to 3.7 billion years ago.  The organisms that existed for the first two billions years, after the origin of life, were all anaerobic organisms. These organisms managed to survive and… Read More »

What is Anoxygenic Photosynthesis

By | October 13, 2021

Photosynthesis is a process, where organisms use inorganic molecules such as carbon di oxide and convert it into carbohydrates (food) using sunlight. In this manner organisms capable of performing photosynthesis can generate energy that helps their growth. Different organisms perform Photosynthesis : Green sulfur bacteria, Acidobacteria, Cyanobacteria, Algae , Plants etc. Depending on the products… Read More »

Photolysis of water

By | October 12, 2021

Plants and some other organisms like Algae and Cyanobacteria are involved in a process of Photosynthesis, which is a multi step process involving many reactions. In Photosynthesis, inorganic substances such as Carbon di oxide, water are used and convert them to organic molecules ( carbohydrates / food) and release oxygen in presence of sunlight. During… Read More »

Importance of Photosynthesis – Photosynthesis in plants (Part- VIII)

By | October 10, 2021

Photosynthesis is a process where green plants and some other organisms make use of carbon dioxide and water in presence of sunlight, and then recombine them into glucose. Energy is stored in the bonds of the glucose molecule and can be used by plants by breaking these bonds by means of another process called cellular… Read More »

Factors affecting photosynthesis – Photosynthesis in plants (Part – VII)

By | October 7, 2021

In the last part of photosynthesis series , we shall look into factors governing the process of photosynthesis in plants and also importance of photosynthesis to both plants and other organisms. Earlier blogs can be read : Part I of Photosynthesis : Introduction Part II – Light Reaction PART III – Calvin Cycle Part VI –… Read More »

Comparison – C3, C4 and CAM pathways ( Photosynthesis in plants- Part VI )

By | September 27, 2021

In the previous 5 blogposts we looked into different important events taking place during the process of photosynthesis in plants. please find the links for those blogs below – Part I of Photosynthesis : Introduction Part II – Light Reaction PART III – Calvin Cycle Part VI – Differences between Light and Dark reactions or Calvin… Read More »

Photorespiration, C4 Pathway and CAM metabolism pathway – Photosynthesis in plants (Part V)

By | September 23, 2021

Evolution (cumulative changes in a population or species through time), is crucial for survival and flourishing of all species or populations. According to endosymbiosis theory, all the eukaryotic life which we see today had evolved from the Archaea bacteria. Evolution has also played an important part in process of photosynthesis- from bacteria to plants. Photosynthesis… Read More »

Difference between Light and dark Reactions – Photosynthesis in Plants Part – IV

By | September 21, 2021

Light and Dark reactions ( Calvin cycle / C3 Cycle) are sequential reactions which occur during Photosynthesis process. In this post we will look into some important differences between these two vital aspects which are essential for synthesis of food in Plants and some other organisms. Difference Light Reaction Dark or Calvin Cycle Place of… Read More »
