what is called the digestive juices contain an enzyme
Answers
Explanation:
The chemical digestion of food is dependent on a whole range of hydrolase enzymes produced by the cells lining the gut as well as associated organs such as the pancreas.

Answer:
ARTICLE Digestive enzymes
Enzymes are globular proteins that control biological reactions. Digestive enzymes speed up the breakdown (hydrolysis) of food molecules into their ‘building block’ components. These reactions occur outside of the cells lining the gut.
Action of sucrase on sucrose
Sucrose binds to the active site on sucrase, and this puts stress on the bond between the 2 sugars that make up sucrose. The bond breaks, releasing glucose and fructose.
Naming and classification of enzymes
There are 2 systems used for naming enzymes:
The suffix ‘-ase’ is used with the root name of the substance being acted upon, for example, when sucrose (sugar) is digested, it is acted upon by an enzyme called sucrase.
The type of chemical reaction involved as the enzyme functions, for example, when sucrase acts on sucrose, it breaks it into a molecule of glucose and a molecule of fructose. This reaction involves adding a water molecule to break a chemical bond and so the enzyme is a hydrolase. All digestive enzymes belong to this hydrolase class.
Enzymes are classified according to the type of chemical reaction catalysed. All digestive enzymes are hydrolases, whereas most of the enzymes involved in energy release for muscular contraction are oxidation-reduction enzymes such as oxidases, hydrogenases and dehydrogenases.
