Enzymes
- Are part of the protein group
- Proteins are made of amino acids
- Proteins are made of amino acids
- Act as biological catalysts
- Control the speed of all chemical reactions in organisms
- Control the speed of all chemical reactions in organisms
- Anabolism: Reactions that synthesise larger molecules from smaller ones
- Reactions that break down large molecules into small molecules
- Reactions that break down large molecules into small molecules
- Enzymes are specific
- One enzyme catalyses only one specific reaction
- They all have the ending 'ase'
- They all have the ending 'ase'
- One enzyme catalyses only one specific reaction
- Lock-and-key model
- The shape of an enzyme in an area known as its active site corresponds to that of a
substance it catalyses
- The shape of an enzyme in an area known as its active site corresponds to that of a
substance it catalyses
- Factors that affect enzyme
activity:
- Warmer temp= faster reaction. Can denature above 40 degrees.
- pH: optimum= 7. Can denature if too extreme
- Warmer temp= faster reaction. Can denature above 40 degrees.
- Co-factors: many enzymes need another molecule to assist
