What are the differences between starch and glucose?
glucose is a type of sugar, and it is combined with starch. sugar is a category, because it could be fructose, glucose, etc.
What happens when enzymes are added to starch suspension?
The enzyme eg. Amylase will break down the starch into sugar.
What observations do you need to expect if starch is present when testing leaf for starch?
It can be observed that when testing for starch their must be a olour change of blue black after iodine solution was added.Before the colour change was green that changed to blue black of the whole procedure is been carried out.
What is the organic compound that reacts when iodine is added to starch solution?
starch
How many grams of glucose must be added to 525 g of 2.5 percent leg mass glucose solution?
how many grams of glucose must be added to 525g of 2.5 percent leg mass glucose solution?and give the furmela?
How would the results of the starch hydrolysis change if glucose was added to the medium?
The starch is a different media. Therefore, by adding glucose to the medium it would throw off the results of the starch hydrolysis significantly.
What is the colour change in glucose when Benedict's solution is added to it and is heated?
Because starch and glucose are two different tests and there are different reactions that can occur in the process of these tests.
Why do green leaves turn blue black when iodine is added?
because the leaves have photosynthesized- glucose is produced. therefore, the excess glucose is converted to starch. The starch is then stored in the leaf-starch is what causes the "green" leaf to turn blue black, as iodine turns blue-black when it reacts with starch.:P
What color is glucose when lugol's iodine is added?
I did this lab experiment in my biology class. When Lugol's indicator is added to glucose, it turns to a dark green colour for starch it turns black and for surcose it turns yellow.

What happens when enzymes are added to starch suspension?
The enzyme eg. Amylase will break down the starch into sugar.
Which reacts to iodine glucose or starch?
Starch turns blue when Iodine is introduced. Added: Though it's not quite a chemical reaction, Iodine will give starch a bluish purple color but it stays chemically UNchanged. Iodine stays reddish brown with glucose and many other oligosaccharides (up till about 10 to 15 monomeric glucose units)
Why does amylase need to be added to the pancreas again?
Since amylase is found in our saliva, the pancreas has to add it again because when we eat starch we need it to break down into maltose, and when it is broken down, we swallow and let the maltase from the small intestine break it down more so it turns into glucose molecules, making it easier to digest.
How do starch turn into sugar?
Starch is made of many glucose molecules attached together by glycosidic linkage, which removes water from an equation. To break down starch into sugar, water needs to be added into the glycosidic linkages (a process called hydrolysis). The water completely breaks the starch in to individual sugar molecules.
What normally happens when iodine solution is added to starch?
it will change into blue black colours.
Is starch carbohydrates?
Starch is one of the ways plants store glucose as energy. It is either is the form of helical amylose or branched amylopectin. Starch is a polysaccharide made from the monomers or monosaccharides alpha glucose.
How do you separate cellulose from a mixture of glucose starch and cellulose?
Water is added to the mixture and the mixture is filtered. Sucrose which can dissolve in water passes through the filter but starch and cellulose which do not dissolve, remain as residue. Starch is hydrolyzed to glucose, which will then dissolve in water. Filtration of the above mixture will leave cellulose as the residue.
