Because it plays an important role in building complex molecules from simple ones, and breaking some molecules to release the energy stored in them.
Catabolism and Anabolism reactions are essential for living cells.
Because catabolism process breaks up some molecules to release the energy stored in them, while anabolism builds up complex molecules from simple ones.
The biological importance of enzymes.
Because they speed up chemical reactions occurring inside living organisms without taking part in them by decreasing the activation energy needed for these reactions to occur.
Amylase is a simple enzyme, while Catalase is a complex one.
Amylase is a simple enzyme because it is composed of simple proteins, while Catalase is a complex enzyme because it is composed of complex proteins and non proteins parts.
Temperature affects enzyme activity.
Because each enzyme has a temp. on which it becomes most active "optimum temperature", when its temp. increases or decreases, its activity decreases until it stops
When the temp. of an enzyme increases more than its optimum temperature, its activity decreases gradually until it stops.
Due to the change of the natural structure of enzyme.
PH of solutions affect enzyme activity.
because its composed of amino acids which contain acidic carboxyl groups COOH- and basic amine groups NH2.
