The precision, accuracy and uncertainty in the data is commented on. These large molecules must be broken down into smaller molecules through the mechanical and chemical mechanisms.

Outline the digestion of maltose, maltotriose and dextrins into glucose. These lipids combine together with proteins and phospholipids to form lipoproteins. My result would be expressed in time as the solution that takes more time to decolorize would be the one with a smaller concentration of glucose, so the one on which the action of amylase occurred the less.

Improvements are given which are possible within the context of a school laboratory. Enzymes released by the small intestines break down macromolecules into smaller molecules called monomers through catabolic reactions hydrolysis is the type of specific reaction.

This difference should merge significantly in this experiment as starch is closed in the grains hulls which are mostly made of fibres. Although the 0.

Effect of amylase concentration on starch digestion

The increased presence of sodium chloride did lower the enzyme activity of amylase, as predicted in the hypothesis, and as accepted as a scientific fact. The numbers here, match with numbers on the two diagrams above and below. In order to observe the effect of NaCl concentration on the activity of enzyme more efficiently, it would be apt to utilize even more miniscule concentrations of sodium chloride. As sodium chloride concentration increased, the average rate of reaction decreased at a fairly constant rate. These last two compounds give a purple solution that would get later oxidised by the presence of glucose. Food is moved unidirectionally along the alimentary canal in a caudal direction mouth to anus contraction of circular and longitudinal muscle of the small intestine helps mix mechanical digestion the food with enzymes and moves the semi-digested food bolus along the gut in a process called peristalsis These muscles are made up of smooth muscle The process by which continual waves of contraction and relaxation peristalsis of the circular and longitudinal muscle occur along the muscle layers surrounding the small intestine is controlled by the autonomic nervous system Food is transported slowly through the small intestine to allow for maximum digestion and absorption of nutrients U 6. This process cause a change in colour of the solution, going from purple to transparent. Describe transport of glucose into and through villi capillaries. Moreover, another problem during the procedures could have occurred with the mixing of amylase with sodium chloride. The rate of reaction is actually slow due to the body temperature.

The student should compare the results of their investigation with what would be expected; reference published data or theoretical texts.

This change could perhaps produce results that are closer to those that were hypothesized. The quantity of the data is commented on both MV and RV.

As sodium chloride concentration increased, the average rate of reaction decreased at a fairly constant rate. Limitations: The variation in results is reported, showing the strength of the conclusion.

This change could perhaps produce results that are closer to those that were hypothesized. This suggests that too much sodium chloride was incorporated throughout the experiment, compared to the amount of amylase. Time discrepancy in the amount of time sodium chloride was allowed to interact with amylase between each trial It allowed more time for the sodium chloride in some micro tubes to denature amylase than in other micro tubes, allowing the possibility for further decrease in the enzyme activity for amylase used in some trials compared to other trials. Outlier data or irregularities in the data are addressed. Enzymes are produced by ribosomes in the pancreatic gland cells, excreted by exocytosis into smaller ducts, which converge to form the pancreatic duct. As a matter of fact Ive chosen white-refined flour because it has a high amount of net carbs and proteins but a very little amount of fibre while kamut flour has a higher amount of fibre and proteins compared to white refined flour but a significantly lower amount of net carbs.

In the range of pH1 to pH6. A short explanation for the question is given to establish its importance and relevance. List materials absorbed by the villi cells of the small intestine.
