and carbon dioxide by yeasts. This operation is effective and extracts the solar energy stored in the starch. * Enzymes are proteins which catalyse‚ or speed up‚ biological reactions. Enzymes usually have an -ase suffix‚ eg. lactase‚ protease‚ amylase and so on. Biological reactions are the reactions that occur in living things. For example‚ when we eat food we need to digest it. Without enzymes in our bodies‚ digestion could take weeks instead of a matter of hours. Enzymes are specific for a certain

complicated food particles into molecules (Catabolism) like this: Fat breaks down into Fatty acids by using an enzyme called Lipase. Protein breaks down into Amino Acids by an enzyme called protease. Starch breaks down into sugars by using an enzyme called amylase. These enzymes are produced by hormones. The hormones are activated when you eat. Once we have broken these down‚ we can then build them back up again into a collection of molecules (Anabolism) so we can digestive them and use them in our cells to

When the plate is flooded with iodine‚ where there is a clearing then that bacteria can secrete amylase. There was a clearing only around Bacillus subtilis on the plate meaning that it can secrete amylase. Staphylococcus aureus and E. coli did not have this clearing meaning they can not secrete amylase. Casein agar is a complex that tests for the ability of a bacterium to secrete a proteinase enzyme that can break down the protein casein‚ which is

INTRODUCTION: Dental caries is one of the most common chronic childhood diseases worldwide. 1 It is initiated by the consumption of fermentable carbohydrates which are converted into organic acids by bacteria in dental plaque. These acids cause a fall in the salivary pH and result in demineralization by the loss of calcium and phosphate ions from the subsurface of enamel. 2 Prevalence of dental caries was seen to be 61% in children between 6 – 12 years 3 and those consuming sugar substances were at a 4.8 times

The water molecule H2O is split in the mechanism of hydrolysis‚ hydrogen cations and hydroxide anions. When the enzyme catalyzes its reaction inside the cell‚ it is referred to as intracellular hydrolases. When the enzymes secreted from the organism to catalyze reactions outside the cell‚ it

Epidemic Parotitis Fever‚ muscle aches‚ loss of appetite‚ exhaustion‚ swollen salivary glands‚ these are all possible symptoms of mumps‚ also known as epidemic parotitis (Mumps‚ CDC). All of these symptoms are caused by a viral infection;there is a vaccine to this virus to help protect humans from the horrible disease. The mumps virus‚ once inside the body‚ will spread to the throat‚ nose‚ mouth‚ and salivary glands by way of mucus and saliva. While it spreads‚ it can cause the symptoms previously

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
