Enzymes

• Metabolism: the sum of all the chemical reactions that occur in an organism
• Solar energy: the energy that comes from the sun
• Cellular energy: the energy stored in the chemicals found in cells
• Catalysts: have the ability to change the rate of chemical reactions without being used up in the reaction
• Enzymes: protein catalysts found in living organisms
• Substrate: the chemical or chemicals with which the enzyme reacts
• Product: the chemical or chemicals made in the reaction
• Active site: the place on the enzyme where the substrate attaches and the reaction takes place
• Enzyme specificity: The ability of an enzyme to only catalyse a specific reaction
• Denatured: when an enzyme has permanently loss its function due to loss of shape
• Bioprocessing: the use of organisms, cells or enzymes to make specific products
• Immobilised enzymes: biological catalysts attached to an inert material chemically or physically
• Bioreactor: a vessel in which cells, organisms or enzymes are placed to manufacture specific products
• ATP: traps and transfers energy for cell reactions
• NAD: traps and transfers hydrogen ions and electrons in cell reactions
• NADP: traps and transfers hydrogen ions and electrons in cell reactions
