type of complex carbohydrate with large polysaccharide molecules that are made up of hundreds of glucose subunits. The digestion of starch begins in the mouth with the enzyme amylase and continues in the small intestine. Maltose‚ a disaccharide‚ breaks down the large polysaccharide molecules. Maltase‚ also found in the small intestine‚ splits each maltose molecule in to two glucose molecules that can be absorbed into the bloodstream. The experiment will be performed by adding amylase

Khalaf (2003)‚ a question was raised and discussed for guiding the study. The question was that‚ would the production rate of citric acid (CA) by Aspergillus niger ATCC9642 from whey can be affected by different specific concentration of sucrose‚ glucose‚ fructose‚ galactose riboflavin‚ tricalcium phosphate and methanol in surface culture process? The focus of the investigation was to produce citric acid by

Discussion The name of enzyme involved in this experiment is salivary amylase‚ which presents in our saliva. Salivary amylase catalyses the breakdown of complex sugar‚ such as starch‚ into a simple sugar‚ such as glucose. In this experiment‚ the optimum temperature for salivary amylase to function is 37˚C. Above the optimum temperature‚ the kinetic energy in the substrate and enzyme increases. The number of collisions between substrate and enzyme also increases‚ but

to pH 3.3‚ ptyalin was totally inactivated in 20 minutes at 37°C. In contrast‚ 50% of amylase activity remained after 150 minutes of exposure to gastric juice at pH 4.3.[5] Both starch‚ the substrate for ptyalin‚ and the product (short chains of glucose) are able to partially protect it against inactivation by gastric acid. Ptyalin added to buffer at pH 3.0 underwent complete inactivation in 120 minutes; however‚ addition of starch at a 0.1% level resulted in 10% of the activity remaining‚ and similar

The purpose of this experiment was to study the effects of ethanol on the cellular respiration of mealworms. Cellular respiration is the process by which cells harvest the energy stored in food. It is the intake of oxygen and energy in the form of glucose‚ and the cells ability to break it down into carbon dioxide‚ water‚ and energy required for the body to function. More scientifically‚ it is a three-step pathway that produces ATP (adenosine triphosphate.) The three stages of cellular respiration
