Post-glycolysis processes Glycolysis is a process that involves: Glucose + 2 NAD+ + 2 ADP + 2 Pi → 2 pyruvate + 2 NADH + 2 H+ + 2 ATP Glycolysis could not continue indefinitely if all NAD+ was used up and glycolysis would cease. Organisms must be capable of oxidizing NADH back into NAD+ … Read more
Glycolysis is the primary stage in the process of breaking down glucose in order to obtain energy to power the cell’s metabolism. The majority of living organisms perform glycolysis as a part in their metabolic process. This process does not require oxygen, which is why it is considered anaerobic. Glycolysis happens in the cytoplasms of … Read more
Pyruvate is a component of the process of lactic acid and alcohol fermentation in anaerobic conditions. in an aerobic state, pyruvate loses carbon dioxide and hydrogen, and transform into Acetyl CoA and enter the TCA cycle. It can as well, enter the biosynthetic pathways. If there is a drop in levels of glucose, pyruvate goes … Read more
Numerous carbohydrates, including glucose, meet their catabolic end in Gycolysis after being transformed into glycolytic intermediates. Most significant are glycogen and starch, which are storage polysaccharides that are either in cell walls (endogenous) or in the diet. The disaccharides are maltose. Lactose, trehalose. and sucrose, and the monosaccharides fructose and mannose and galactose. Dietary Polysaccharides … Read more
What is Control Group? Definition of Control Group A control group is a set of subjects in a scientific experiment who do not receive the treatment or intervention being studied, serving as a benchmark for comparison against the treatment group to determine the effect of the variable under investigation. Importance of Control Group The control … Read more
What is Cell membrane or Plasma Membrane? Definition of Cell membrane or Plasma Membrane The cell membrane, also known as the plasma membrane, is a semi-permeable biological barrier that surrounds and protects the cell’s interior from the external environment, regulating the passage of molecules in and out of the cell. Cell Membrane Composition The cell … Read more
Whittaker’s Five Kingdom Classification brings evolutionary changes in classification system of organisms. Since the centuries, biologists are trying to classify organisms in different ways. Even, Greek philosopher and polymath Aristotle tried to classify organisms on the basis of their habitats, such as whether they lived on land, water, or air. Then Carolus Linnaeus proposed a … Read more
What is Genus? Definition of Genus A genus is a taxonomic rank in biological classification that groups together species with shared characteristics or evolutionary lineage, positioned above species and below family. Classification System The Naming System In the realm of biological taxonomy, the system of binomial nomenclature stands as a cornerstone for naming organisms. This … Read more
What is Experimental Group? Definition of Experimental Group The experimental group, in scientific research, refers to the group subjected to specific changes or treatments in a variable to observe and evaluate potential outcomes, in contrast to a control group which remains unaltered or standardized for comparison. How Does an Experimental Group Work? In the context … Read more
What is Endosymbiotic Theory? Definition of Endosymbiotic Theory The Endosymbiotic Theory posits that certain organelles in eukaryotic cells, specifically mitochondria and chloroplasts, originated from free-living prokaryotic cells that were engulfed by ancestral eukaryotic cells, leading to a mutually beneficial symbiotic relationship. Origin of the eukaryotic cell 1. Gene Trees and the Complexity of Eukaryotic Origins … Read more
