What are amylases? Amylases are enzymes that break down starch or glycogen. Amylases are produced by a variety of living organisms‚ ranging from bacteria to plants and humans. Bacteria and fungi secrete amylases to the outside of their cells to carry out extracellular digestion. When they have broken down the insoluble starch‚ the soluble end products such as (glucose or maltose) are absorbed into their cells. Amylases are classified based on how they break down starch molecules i. α-amylase

Cellular Biology furthers technology-Enzymes in the Dairy Industry Since ancient times‚ enzymes have played an important role in food production. Especially in the diary industry‚ some enzymes are required for the production of cheese‚ yogurt‚ and other dairy products‚ while others are used in a more specialized fashion such as improving texture or flavour of the product. Enzymes are used to catalyze the desirable reactions in industrial processes. Today‚ enzyme applications in such processing get

was designed to investigate the effects of temperature on reactions between the enzyme catalase found in animal tissue with the substrate H2O2. The hypothesis stated that an increase in the temperature of the substrate would create a subsequent increase in the rate of reaction between the enzyme and the substrate. This hypothesis was tested by immersing 1cm cubes of animal tissue (sheep liver) which contained the enzyme catalase into the substrate (H2O2 ) mixed with detergent which foamed showing a

Is the Chicken Ceremony a superstition‚ or is it a supper? Why are chickens important in the Village Valle del Sole? The Village Valle del Sole is located in one of the most isolated parts in Italy‚ so people living there are easily influenced by the lore that is going around the whole village.

Bermuda’s Feral Chicken Problem. By Justin M. Corday. One of Bermuda’s most pressing and rapidly escalating animal problems is the emergence of the wild chicken population. The Bermuda Agriculture and Fisheries Department estimate that there are about 30‚000 feral chickens that exist in large and small groups throughout the 22 square miles of the Island. Previous attempts to control the population have not worked and the number is rising. This is a domestic challenge that can no longer

ENZYMES LABORATORY REPORT Introduction The utilization of any complex molecule for energy by an organism is dependent on a process called hydrolysis. Hydrolysis breaks complex molecules into simpler molecules using water. Similarly‚ the process that is the reverse of this is called dehydration synthesis‚ which removes water from simpler molecules. However‚ because hydrolysis occurs very slowly‚ living organisms use biochemical’s called enzymes to speed up the reaction. In this lab exercise
