processes that occur in organism.

Types of metabolismANABOLISM
CATABOLISM
6.
ANABOLISMIn anabolic reactions, simple
substances join to form more
complex substances.
Example can be photosynthesis in plants
Sunlight energy
Is used
7.
CATABOLISMIn catabolic reactions complex
substance are broken down into simple
substances.
Example can be cellular respiration in cell
C6H12O6+6O2
6H2O + 6 CO2+Energy

Why we need catabolic reactions?Generally carbohydrates, lipids, proteins,
nucleic acids are broken down to yield
energy and also to get raw materials for
building up needed molecules.
10.
Stages of catabolism1) digestion and hydrolysis of
macromolecules up to monomers
2) conversion of monomers to acetylCoA
3) Krebs cycle, Electron transport chain,
synthesis of ATP
11.
During first stageCarbohydrates are broken down into
monosaccharides ( generally glucose)
Lipids are broken down up to glycerol and fatty
acids
Proteins are broken down up to amino acids
Nucleic acids are broken down up to nucleotides
12.
13.
During second stageall monomers turn into Acetyl-CoA
14.
During the third stageAcetyl-CoA
enter to Krebs
cycle and ETS
After ETS ATP
is produced
