Importance of Enzymes to Life
Catalyst
A catalyst is a molecule which is able to speed up a chemical reaction, but remains unchanged in the reaction.
Biological Catalyst
Means that it is a catalyst that is produced by a living thing.
Enzymes are a particular group of proteins.
Without Enzymes
Without enzymes these reactions would not occur fast enough.
Therefore metabolism would be too slow for life to exist.
Biological Catalysts
Therefore:
Enzymes are known as Biological Catalysts, and this makes them so vital to life.
Chemical Reactions
As a biological catalyst enzymes are able to speed up specific chemical reactions and therefore allow metabolism to occurs at a rate fast enough for life to occur.
Life occurs by millions of chemical reactions taking place.
Metabolism
Metabolism is all the reactions which occur within the cell
All of these reactions are controlled by enzymes.
For example:
- Respiration
- DNA synthesis
- Protein synthesis
- Cell replication (Mitosis)
