a container in which a living thing/cells/enzymes are used in the production of something useful, e.g. during fermentation using yeast, yogurt production using bacteria, etc.
highly specific biological catalysts, proteins with a definitive folded shape and are affected by temperature, pH,. They control the rate of metabolic reactions such as respiration, photosynthesis, digestion and assimilation.
enzyme which is fixed to an inert material by chemical or physical means, e.g. trapped in beads or gel so that it will react with, but not mix with, its substrate.
Rate of enzyme activity
the speed at which enzymes catalyse a reaction.
changes in the shape of an enzyme (protein) due to extreme conditions, such as high temperature, unsuitable pH, or the presence of certain chemicals. If these changes are permanent they destroy the activity of the enzyme and the enzyme is denatured.
best or most favourable conditions for growth, reproduction, enzyme activity, etc.
one enzyme will catalyse only one reaction. The active site of an enzyme is not a fixed shape. It can change slightly to better fit the shape of the substrate when forming the enzyme-substrate complex.
