OVERVIEW OF METABOLISM
Metabolism is a central theme in biochemistry metabolism keeps cells and
organisms alive. It gives them the energy to carry on and the building blocks required
for growth and propagation.
Metabolism is the sum total of all the chemical reactions that take place in a living
organism
STAGES OF METABOLISM
Stage I (Biodegradation)
Large molecules in food are broken down into small units. This Stage involves
digestion and absorption
Stage II (Biosynthesis)
Small molecules are converted into a few very simple units that play the central
role in metabolism
Stage III (Energy Production)
Consist of the energy production mainly associated with the Citric Acid Cycle
(Krebs Cycle), electron transport chain (ETC) and oxidative phosphorylation
SUBTYPES OF METABOLIC REACTIONS
1. Catabolism
- includes all metabolic reactions in which large molecules are broken
down to smaller ones
2. Anabolism
- includes all metabolic reactions in which small molecules are put
together to form larger ones
