Chemical and Physical Processes of Digestion NAME: LAB TIME/DATE: Carbohydrate Digestion The following questions refer to Activity 1: Assessing Starch Digestion by Salivary Amylase. 1. At what pH did you see the highest activity of salivary amylase? Why? 2. How do you know that the amylase did not have any contaminating maltose? 3. What effect did boiling have on enzyme activity? Why? 4. Describe the substrate and the subunit product of amylase. The following questions refer

To investigate the affect that change in pH levels has on a particular enzyme‚ in this case amylase. Hypothesis: In this investigation I expect as the pH reaches the optimum level‚ the rate of reaction will be fastest‚ compared to other pH levels. It is also suspected that after the enzyme has reached optimum level the enzyme activity will decrease. Through further study of the optimum level of amylase I found that the enzyme usually has an optima pH of 8. It is known that the pH of an enzymes

Digestion is a process in which the food that we eat is broken down into tiny nutrients to be taken in by the body. Within the human digestive system‚ chemical and physical reactions occur that allow for the digestion and the absorption of proteins into the bloodstream. The purpose of this paper is to show how chemistry relates to the daily functions within the body. There are two types of digestion processes‚ which are called mechanical and chemical digestion. Mechanical digestion includes the

Poem at 39 and Piano Poem at 39 is about a woman describing the relationship with her father. She first talks about how she misses him but the poet portrays a subtle sense of dislike and resentment. She says he was tired when she was born ‘How I miss my father I wish he had not been so tired when I was born. This makes her feel like she is not wanted as she has so many other siblings. A child that age would feel very bad if her father did not give it their love and attention and as they get older

It is effectively a diagnosis of exclusion: the finding of a very high serum amylase activity is very suggestive but is not on its own diagnostic

EXPERIMENT NO. 12 DIGESTION IN THE STOMACH ABSTRACT____________________________________________________________________________ Digestion refers to the mechanical and chemical breakdown of food into smaller components that can undergo absorption. The objective of this experiment is to investigate mainly the process of digestion in the stomach. The conditions at which the enzymes responsible for the digestion process were determined. Also‚ the total and free acidity of gastric juice of the sample

Summary of IAS 39: IAS 39: Financial Instruments: Recognition and Measure was first adopted by European Union for annual periods beginning on or after January 1st 2005. The goal was to provide principles for recognising and measuring financial assets‚ financial liabilities (including derivative financial instruments) and some specific contracts to buy and sell non-financial items. Initial Recognition: Financial asset or financial liability is only recognised on balance sheet when and only when

ruminants like cattle enables them to efficiently use high roughage feedstuffs‚ including forages. Their digestive system is composed of the mouth‚ tongue‚ gall bladder‚ pancreas‚ the four compartment stomach (rumen‚ reticulum‚ omasum‚ and abomasum)‚ salivary glands‚ the small intestine (duodenum‚ jejunum‚ and ileum)‚ esophagus and the large intestine (cecum‚ colon‚ and rectum) (Brooker‚ 5). Mouth and Teeth A ruminant animal uses its mouth and tongue to harvest forages and consume feedstuffs during

The Process of Digestion Over the course of time there have been many difficult questions and theories about everyday life. Using physiology & chemistry‚ those questions have been able to be answered. From the mixture of gases in the air we breathe to the organic substance of plastic or paper‚ chemistry can be seen everywhere. However‚ most people mistook the power of chemistry in our own bodies. How is it that a simple slice of bread‚ once consumed‚ can turn into fuel for the human body

the gastrointestinal tract plus the accessory organs of digestion (the tongue‚ salivary glands‚ pancreas‚ liver‚ and gallbladder).[1] In this system‚ the process of digestion has many stages‚ the first of which starts in the mouth. Digestion involves the breakdown of food into smaller and smaller components‚ until they can be absorbed and assimilated into the body. Chewing‚ in which food is mixed with saliva begins the process of digestion. This produces a bolus which can be swallowed down the esophagus
