maltose or starch contamination. Tube 4 was a starch control (with the same water) that showed no maltose‚ and tube 5 was a maltose control (also with water) that showed no starch. If control tubes 3‚ 4‚ or 5 were not done‚ then what is perceived as digestion might really be starch or maltose contamination. Saliva would not be active in the stomach because the stomach pH is too low. Boiling inactivates‚ or denatures‚ enzymes. 10. Tubes 2‚ 6‚ and 7 showed the effect of pH on amylase activity. The results

Digestion is the process in which the body breaks down food into particles that can be used for nourishment. The stomach is not the only organ involved in the digestion process. A series of organs comprise the human digestive tract‚ including the mouth‚ esophagus‚ stomach‚ small intestines‚ liver and large intestine. Each organ in the digestive tract plays an integral part in the digestive process. The food enters the mouth‚ where it is masticated and prepped for digestion. The mouth is comprised

Chew Your Food SLOWLY When people think digestion they most often think of intestines and their stomach. The truth is that the digestion process actually begins in the mouth. The process of chewing is a vital component of the digestive process. The action of chewing mechanically breaks down very large amounts of food molecules into smaller particles. This results in food having increased in surface area‚ an important contributing factor to good digestion. Chewing your food well allows the food to

How well did the results compare with your prediction?__Boiling caused amylase to be denatured‚ thus inactivating the enzyme. Freezing has no effect. The function of an enzyme is directly related

Free State‚ 4 August 2012 ABSTRACT The aim of this study was firstly to determine if any heavy metals were present in the paint used on toy cars‚ and secondly to determine what other elements‚ and in which quantities‚ were present. Two different digestion methods were followed‚ and both confirmed the presence of Ba and Fe‚ although the concentrations obtained by each method differed: higher values m/m% was obtained for all samples digested by HCl than for samples digested by acetic acid.

When rationally thinking about the gastrointestinal tract or digestion‚ nearly all of its functions are regulated by the autonomic nervous system‚ or involuntary‚ meaning that we do not consciously have to contemplate digestion for digestion to occur. With this being stated‚ it would make sense that almost the entire gastrointestinal tract is made up of smooth muscle. Smooth muscle is very distinctive from the other types of muscle in the body due to the fact that it is not controlled consciously
