Catabolism
|
chemical reactions that release energy from the decomposition of complex organic molecules.
|
|
Carbohydrates
|
organic molecules that contain carbon, hydrogen, and oxygen in ratio.
|
|
Monosaccharides
|
simple sugars containing from 3 to 7 carbon atoms.
|
|
Oligosaccharides
|
composed of 2 to about 20 monosacharide molecules.
|
|
Polysaccharide

|
Hydrolytic Enzymes
|
Enzymes are mainly this. They leave the cell and break down, by the addition of water, large substrates into smaller components, which can then be transported into the cell.
|
|
Oxidative Catabolism
|
requires the presence of molecular oxygen.
|
|
Fermentative Catabolism
|
does not require oxygen but may occur in its presence.
|
|
