What do you mean by Fate of Pyruvate? Pyruvate, the end product of glycolysis, represents a central intermediate in cellular metabolism. Glycolysis is a sequence of enzyme-catalyzed reactions in which glucose is broken down into two molecules of pyruvate, generating ATP and NADH in the process. This pathway, also known as the Embden-Meyerhof-Parnas (EMP) pathway, … Read more
What is Glycogen? Definition of Glycogen Glycogen is a branched polysaccharide made of glucose units that serves as the primary form of glucose storage in animals, fungi, and bacteria. It is primarily stored in the liver and muscles and acts as a readily mobilized energy source when the body needs glucose. Characteristics of Glycogen Glycogen … Read more
What is glycolysis? Definition of glycolysis Glycolysis is a metabolic process in which glucose, a six-carbon sugar, is broken down into two three-carbon pyruvate molecules, producing a net gain of two ATP and two NADH molecules. This anaerobic pathway occurs in the cytosol and is a key step in cellular energy production. Major Features of … Read more
What is the Electron Transport Chain? Electron transport chain Definition The electron transport chain is a series of protein complexes and molecules located in membranes, where electrons are transferred through redox reactions to generate a proton gradient that drives ATP synthesis via oxidative phosphorylation. Electron Transport Chain Animation Video Fundamentals of the Electron Transport Chain … Read more
What are Nostoc? Classification of Nostoc Nostoc belongs to the group of cyanobacteria, which are known for their ability to photosynthesize and fix nitrogen. The classification of Nostoc follows a systematic hierarchy that categorizes it at different taxonomic levels. Domain: Bacteria Phylum: Cyanobacteria Class: Cyanophyceae Order: Nostocales Family: Nostocaceae Genus: Nostoc Definition of Nostoc Nostoc … Read more
What are bacteria? Definition of Bacteria Bacteria are microscopic, single-celled prokaryotic organisms lacking a nucleus and membrane-bound organelles, found in diverse environments, and essential for ecological processes, industrial applications, and human health. Origin and Early Evolution of Bacteria Bacteria represent some of the earliest life forms on Earth, with origins dating back approximately 4 billion … Read more

What is Repeater Pipette? How Repeater Pipettes Work Repeater pipettes enable the precise and repetitive dispensing of liquid in equal volumes. They improve efficiency by eliminating the need for repeated aspiration. Here’s a breakdown of their operation: Mechanism of Action Parts of Repeater Pipettes Repeater pipettes are designed for precise and efficient liquid dispensing. They … Read more
What is mouth pipette? Principle of Mouth Pipette The working principle of mouth pipetting is based on the creation of a pressure differential, which allows for the movement of liquid into a pipette through suction. This method involves the use of a glass capillary tube, where one end is submerged in the liquid to be … Read more
