In which organ of a digestive tract starch is hydrolysed in a maltose ?
(a) Mouth
(b) Stomach
(c) Small intestine
(d) Liver
Answers
Answer:
The organ in which starch is hydrolysed into maltose, is the mouth. The hydrolysis is achieved by the enzyme amylase that is produced by saliva in the mouth.
Explanation:
Digestion is the process by which food nutrients is broken down into its simplest form to necessitate absorption. Digestion can either be mechanical or chemical. Mechanical digestion involves the break down of food mecahnically while chemical digestion involves digestion of food using biochemical molecules, enzymes like lipase, amylase and proteases.
Digestion of starch begins in the mouth where starch is hydrolysed to the disaccharide called maltose by the action of the salivary amylase. The process of digestion of starch is continued in the intestines by help of enzymes such as maltase, lactase, sucrase and pancreatic amylase.
Answer:
Starch is hydrolysed in a maltose through (a) Mouth.
Explanation:
In the digestion process, the salivary enzyme amylase begins to break down the food into maltose, maltase breaks down maltose into glucose. This process is also called ingestion. The combined action of teeth and saliva modifies the food from large particles to soft mass that can be swallowed and reach the other part of the digestive system. It is one of the life process that breaks down sugar and fats for energy.
