What else can I help you with?
What conclusion can you draw when an experimental sample gives both a positive starch and a positive maltose test after incubation?
The positive starch test indicates the presence of starch in the sample which could have been broken down to maltose. The positive maltose test confirms the presence of maltose. Therefore, it can be concluded that the sample initially contained starch which was subsequently broken down to maltose during incubation.
What conclusions can you draw when an experimental sample gives both a positive starch test and a positive maltose test after incubation?
Starch digestion (hydrolysis) is incomplete
What conclusions can you draw when an experiment sample givs both a positive starch test and a positive maltose test after incubation?
When an experiment sample yields both a positive starch test and a positive maltose test after incubation, it suggests that starch was initially present and has been broken down into maltose during the incubation process. This indicates the activity of amylase, an enzyme that catalyzes the hydrolysis of starch into simpler sugars like maltose. The positive starch test indicates that not all starch was fully converted, while the maltose test confirms the presence of the product of starch breakdown. Overall, this suggests effective enzymatic activity in the sample.
What does IKI solution test for?
IKI solution is used to test for the presence of starch. Starch will turn blue-black in the presence of IKI solution, indicating a positive test result for the presence of starch.
What is a positive test result for starch?
A positive test result for starch is the formation of a blue-black color when iodine solution is added to the sample being tested. This color change indicates the presence of starch in the sample.
Is E. coli positive or negative for starch agar test?
E.coli does not digest the starch on a starch agar plate, therefore it does not produce amylase making it negative.
Is there starch in a mcdonalds happy meal burger?
yes but im not sure how much we did a test in biology that was positive for starch
What is positive color for iodine test?
The positive color for the iodine test is a dark blue or black color. This color change indicates the presence of starch in the test substance.
Which part of a palisade cell would test positive for starch?
The chloroplast located in the leaves
In the lugols solution test what color is a positive test?
A positive Lugol's solution test will result in a dark blue or black coloration, indicating the presence of starch.
How will bean seeds give a positive test for starch?
The seed uses the starch until it become an adult plant or in other words, until it is fully grown to produce its own food. Inside the cotyledon, starch is present and thus, gives a positive result for starch :)
Why starch does not give with fehling test?
Starch does not give a positive result in the Fehling test because starch is a polysaccharide made up of glucose units linked together in a way that does not allow the formation of free aldehyde or ketone groups required for the Fehling test to detect reducing sugars. Since starch is a larger molecule, it does not react with the Fehling reagent designed to detect the presence of smaller reducing sugars like glucose and fructose.
