What is amphibolic pathway?

By | November 9, 2021

Amphibolic pathway can be described as a kind of biochemical pathway which involves both Anabolism and catabolism pathways. The term amphibolic pathway is coined by B. Davis in the year 1961. Catabolism : A biochemical pathway where large molecules are broken down into smaller molecules. It can be by means of Hydrolysis and Oxidation. Hydrolysis… Read More »

Electron transport system and Oxidative phosphorylation – Cellular respiration ( Part – V)

By | November 1, 2021

By using electron transport system and oxidative phosphorylation steps, the cell utilizes energy stored in NADH + H+ and FADH formed during glycolysis and Krebs cycle. The Electron Transport System also called the Electron Transport Chain is a metabolic pathway present in the inner mitochondrial membrane, where electrons available from oxidation of NADH and FADH2… Read More »

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 »

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 »
