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.
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
ANABOLIC PATHWAY
CATABOLIC PATHWAY
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
Carbohydrates
lipids etc.
PATHWAYS OF CARBOHYDRATE METABOLISM
GLYCOLYSIS
CITRIC ACID CYCLE
GLUCONEOGENEIS
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.
