METABOLISM is defined as the SUM of all the CHEMICAL REACTIONS in an organism, which are regulated by ENZYMES.
The energy transferred by RESPIRATION in cells is used by the organism for the continual ENZYME CONTROLLED processes of metabolism that create new molecules.
ENZYMES are crucial as they control reactions, transforming SUBSTRATES into PRODUCTS.
Reactions for metabolism include:
1. Multiple GLUCOSE molecules joining to form STARCH and CELLULOSE in plants, and GLYCOGEN in animals.
2. Forming LIPIDS from ONE molecule of GLYCEROL and THREE molecules of FATTY ACIDS.
3. Forming AMINO ACIDS by combining GLUCOSE with NITRATE IONS to produce PROTEINS.
4. Breaking down GLUCOSE via RESPIRATION for TRANSFERRING ENERGY to power ALL reactions in the body.
5. Breaking down EXCESS PROTEIN into UREA for EXCRETION.
When you EXERCISE, your body undergoes changes to ensure enough ENERGY is supplied to your CELLS.
