What happened to the starch solution after you have added saliva?
Saliva contains enzymes which catalyse the breakdown of starch to maltose and dextrin. If starch solution is treated with saliva, these simpler sugars will soon start to form, which means the mixture will give the Benedict's test.
Why does iodine stop turning starch blue when saliva is present?
Saliva contains a digestive enzyme that converts starch into sugar.
Why did very little if any starch digestion occur in test tube 4A?
Because the enzyme amylase was denatured. It was boiled first before putting the starch in.
Can saliva break down any substances other than starch?
No, because amylase, like all other enzymes, has a very specific structure. Only one substrate has a shape that is complementary to amylase, which is starch. Any other molecules will be unable to bind to the active site, and so reactions with other substances won't happen.
What is the organ where the chemical digestion of starch begins?
I don't think of it as an organ, but chemical digestion of starch begins in the mouth, using saliva.
Why digestion of starch starts in the mouth?
It does not digest starch faster. The saliva produced before the meal will have a longer time to prepare.
Does saliva contain starch?
Saliva contains the enzyme amylase which breaks down the starch (amylose) into maltose.
How can you tell how quickly the saliva digests the starch?
Starch doesn't digest saliva. The enzyme in saliva digests starch.
The digestion of startch begins in the?
Starch digestion begins in the mouth. Saliva in the mouth enables chemical digestion to take place before starch enters the stomach.
What substances does the enzymes in saliva change starch into?
it contains enzymes which break the starch down to sugar
What happens to starch in a cracker when it react with saliva?
The enzymes in the saliva help break down the starch in the cracker.
Is starch broken down once you chew bread?
Yes it can happen because saliva contain amylase enzyme.
Why the starch has to be boiled before it adding to the amylase?
To destroy any microbes or bacteria that may be present in it.
What kind of food does the saliva acts on?
Saliva acts on starch
What happened to the starch solution after you have added saliva?

How do you explain when we add starch solution saliva dilute alkali and did not presence of starch and presence of glucose?
The enzyme amylase in the saliva broke the starch down into glucose.
Why does iodine stop turning starch blue when saliva is present?
Saliva contains a digestive enzyme that converts starch into sugar.
