Carbohydrate metabolism.pptx

This presentation is all about on the topic 'Carbohydrate Metabolism' prepared to present before higher secondary level students, priority has been given to make it as gullible as it suits for better understanding of the aforesaid audience.

1. A Presentation on Carbohydrate Metabolism Presented by: Chhan Kr Kalita M.Sc. 3 rd Sem., Dept. of Botany Nowgong College (Autonomous), Nagaon

2. METABOLISM, TYPES OF METABOLIC PATHWAYS CARBOHYDRATE METABOLISM MAJOR PATHWAYS OF CARBOHYDRATE METABOLISM GLYC0LYSIS (EMBDEN –MEYERHOF PATHWAY ) CITRIC ACID CYCLE ( KREBS’ CYCLE ) GLYCOGENESIS CONTENTS

3. The chemical processes in living beings that change the food molecules into energy and help them in functioning is simply can be defined as – metabolism. METABOLISM TYPES OF METABOLIC PATHWAYS

4. CARBOHYDRATE METABOLISM Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis, enters into kreb cycle and oxidative phosphorylation to generate ATP. AMPHIBOLIC PATHWAY CO2+ H2O CATABOLIC ANABOLIC FOOD MOLECULES SIMPLER MOLECULES Protein C arbohydrates lipids etc. PATHWAYS OF CARBOHYDRATE METABOLISM

5. Glycolysis is the process in which glucose is broken down to produce energy. It produces two molecules of pyruvate, ATP, NADH and water . Site of production- cytoplasm or cytosol. It occurs in both aerobic and anaerobic organisms . Net production- 2NADH+ 2ATP= 8ATP (Since 1NADH= 3ATP) GLYC0LYSIS ( EMBDEN-MEYERHOF PATHWAY)

6. The Krebs cycle or TCA cycle (tricarboxylic acid cycle) or Citric acid cycle is a series of enzyme catalysed reactions occurring in the mitochondrial matrix , where acetyl-CoA is oxidised to form carbon dioxide and coenzymes are reduced, which generate ATP in the electron transport chain . Net Production- 3NADH+H+ + 1FADH2= 12ATP TCA CYCLE/ KREBs’ CYCLE/ CITRIC ACID CYCLE

7. The biochemical process of preparing glucose from the non-glucose precursors within the cells is called gluconeogenesis . Site of Production- Liver, small intestine and kidneys . GLYCOGENESIS
