Why to destarch a plant?
a leaf (plant) should be destarched before photosynthesis investigations because the starch already present in the plant may mislead the result . hence if a destarched plant is used for the experiment then the amount of starch present at the time of the experiment will be nil and affter the experiment is compleded the amount of starch present in the leaves woul give the rate of photodynthesis as starch id prepared during photosynthesis
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.
What stores more energy starch or fat?
starch gives more energy than sugar because starch is a polysaccharide(polymer of sugar).
What happens if starch is present in leaf?
The presence of starch in plants indicate that photosynthesis has occurred. The process of testing the presence of starch uses iodine solution that turns to blue-black on a positive test.
What happens if you add iodine drops to a non-starch?
If you add iodine to starch the start will turn to a dark color blue/blk because of the enzyne Amylase (in starch), so if it is non starch there will not be a reaction and it will be clear.
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.
Why must you digest starch before you can use it for energy?
Your body cannot use starch because it is a complex carbohydrate. It must be broken down into shorter carbohydrate strings before being converted into energy
Why must leaves be exposed to sunlight for some time before testing for starch?
Because they need the presence of chlorophll in them
What happen to starch if the saliva was boiled before it is mixed with starch?
to remove bacteria in saliva

What types of substances are stored by plants?
starch is one substance stored in plants because starch is not osmotically active
When starch will be used?
You'll need to explain what it will be used for before anyone can suggest which starch will work.
Why can protein and starch not be absorbed directly into the body?
Because starch is a polymer of sugar molecules (lots of them all bound together as a store of sugar) and the cells in the body can only metabolize individual sugar molecules. Therefore the starch needs to be broken up into its individual sugars before it is any use to the cells.
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 pie have starch?
Pies do have starch. It is because of their crusts. The crust has flour, which is a starchy ingredient.
What is the melting point of starch?
None, starch will decompose fully before it boils. :)
Why starch is used as indicator in iodometric titration?
Starch is not used in order to do this. This is because starch is able to form a complex along with the iodine and this is the indicator.
