DIGESTION OF CARBOHYDRATES Digestion of carbohydrate begins in the mouth‚ with the secretion of the enzyme salivary amylase from the serous cells of the salivary gland. This enzyme breaks starch and glycogen into disaccharides. The mucous cells of the salivary gland secrete a mucus‚ which causes the food to stick together‚ and acts as a lubricant to aid in swallowing. The salivary glands are grouped into three categories: the parotid gland‚ submandibular glands‚ and sublingual‚ all located

Experiments investigating the effect of a particular factor on an enzyme-catalysed reaction are commonly used as assessed practicals in Biology. The reason for this is there are a number of factors that can be investigated‚ and therefore‚ a number of factors that can also be controlled. From our lecture‚ we are aware that the following can affect the rate of reaction: 1) Temperature: a. Independent variable: A range of temperatures should be investigated‚ with particular attention

To many people I am bread‚ mayonnaise‚ and breaded chicken. However to the digestive system I am carbohydrates‚ fat‚ and protein. When I am consumed‚ most of me is distributed in your body. However‚ what s not useful is expelled. The digestive system is meant to ingest food through your mouth‚ digest it is by breaking it down‚ ingest it to your bloodstream‚ and lastly excrete it through the anus. In this essay I will guide you through these four phases. Bread is made out of carbohydrates. In the

The purpose of the unknown bacteria lab assignment was to select an unknown bacteria culture and‚ through a series of metabolic tests‚ identify which bacteria genus resided in the pure culture received. A nutrient broth inoculated with bacterial culture (numbered 45‚ henceforth referenced as U45) was selected and a streak plate was made to isolate a pure culture for use throughout the assignment. From the streak plate‚ several slides were made to determine the morphology of unknown 45. A Gram stain

Lipases are released into the bloodstream and break down fats in the bloodstream (from the fats and oils we eat) or travel to adipose cells. Lipases break the glycerol head away from the fatty acids in our
