The mitochondrial electron transport chain is composed of three main membrane-associated electron carriers flavoproteins (FMN, FAD), cytochromes, and quinones (coenzyme Q, also known as ubiquinone because it is a ubiquitous quinone in biological systems). All these electron carriers reside within the inner membrane of the mitochondria and operate together to transfer electrons from donors, like NADH and FADH2, to acceptors, [...]
The following points highlight the three main metabolic pathways to break glucose into pyruvate. The pathways are: 1. Glycolysis 2. Pentose Phosphate Pathway or Hexose Monophosphate Pathway 3. Entner-Doudoroff Pathway. Metabolic Pathway # 1. Glycolysis: Glycolysis (Gk. glykys = sweet, lysis = splitting), also called glycolytic pathway or Embden-Meyerhof-Parnas (EMP) pathway, is the sequence of reactions that metabolises one molecule [...]
In this article we will discuss about:- 1. Meaning of Tricarboxylic Acid Cycle 2. Outline of TCA Cycle 3. Significance. Meaning of Tricarboxylic Acid (TCA) Cycle: Tricarboxylic acid cycle (TCA cycle) is also called citric acid cycle or Krebs cycle (after its discoverer, Sir Hans Krebs). TCA cycle or citric acid cycle is the central metabolic hub of the cell [...]
