Best Answer

Starch is typically broken down by the enzyme amylase pretty effectively. To check to see if the amylase is working properly, you can add the enzyme in a solution of starch and constantly check the concentrations of starch at certain intervals of time using a spectrometer.

Why is starch found in plants?

Glucose for energy is stored as starch in plants. The glucose molecules join up to form starch molecules.


What is the different between animal and plant starch?

Animals do not store glucose in starch molecules, but rather in glycogen molecules. Starch molecules have infrequent branching of glucose chains and as such are not readily broken down into glucose monomers by the enzymes that catalyze the reaction. Glycogen molecules follow the same basic structure as starch molecules, but instead have more branching and consequently are broken down easier. This allows for quicker "burst" energy and is better suited to animals' mobility.


What are the end products of starch hydrolysis?

When the starch is broken down, or hydrolyzed, the end product is glucose molecules.


When glucose molecules link up what substance do they form?

starch molecules


What do digestive enzymes split starch into?

Starch is a polysaccharide made up of a chain of sugar molecules. Digestive enzymes split starch into glucose molecules by breaking up links of the chain.


Are big starch molecules made up of little glucose molecules?

there are a large number of glucose molecules in starch.


What type of food molecule is broken down to glucose by digestion?

Sugars and starches are broken down into glucose.


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 might plant storage organs (such as fruit or tuber) contain both starch and sugar?

Starch and sugar are essentially the same thing. Starch is a polymer (chain) of single sugar molecules. As the starch is made up or broken down, you would expect to find both in the cells responsible for this action.


Gelatinisation of starch?

Gelatinization of starch is a process during which inter molecular bonds of starch molecules is broken down due to the presence of heat or water ,making the starch granules swell.


Do starchy foods provide energy?

Yes. The starch molecule is a string of glucose molecules. When eaten, the starch is broken down by enzymes into individual glucose molecules. Glucose is the human body's primary source of energy.


What enyzmes digest the protein?

for starch - amylase for proteins - protiase for fats and oils - lipase proteins are broken up into ameno acids starch is broken up ito multose then glucose fats and oils are broken up into glycerol
