Which of the following does NOT takes place in the mouth?
Absorption of food
Chemical digestion of starch by amylase
Physical digestion
Ingestion
What does ingestion means?
The process of breaking large food into smaller pieces
The process of taking food into our body by swallowing
The process of releasing enzyme from glands
How does salivary gland helps in digestion of food?
Secretion of enzyme lipase that breaks down lipids into fatty acid and glycerol
Release hydrochloric acid that breaks down protein into amino acid
Release saliva that contain enzyme amylase that breaks down starch into maltose
Which of the following does NOT take place in the stomach?
Physical digestion
Chemical digestion of starch by amylase
Chemical digestion of protein by protease
Hydrochloric acid kills ingested bacteria
One word in the sentence below is wrong. Write down the word:
"In small intestine such as duodenum, colon and ileum, chemical digestion of starch, maltose, protein and lipids takes place"
(a)
Which of the following is NOT the function of liver
Breakdown glucose into amino acid
Store glycogen
Breakdown excess amino acid into urea
Where does absorption of digested food and water takes place?
ileum and rectum
colon and duodenum
duodenum and rectum
ileum and colon
Egestion takes place in rectum and anus. What does egestion means?
The process of taking food into our body
Removal of undigested food from our body
The process of breaking large food molecules into smaller chemical
Which of the following enzyme action is FALSE?
Amylase breaks down starch into maltose
Maltase breaks down glucose into maltose
Protease breaks down protein into amino acids
Lipase breaks down lipids into fatty acids and glycerol
Protease breaks down protein into amino acid. What is the differences between protease in the stomach and the protease in the duodenum?
The protease in duodenum also break starch, maltose and lipids
The duodenum is warmer so they work best at different temperature
The stomach is acidic so they work best at different pH
There is no differences. They do the same thing.
