starch from grain is somewhat more complex than fermentation of sugars because starch must first be converted to sugar and then to ethanol. · Starch is converted enzymatically to glucose either by diastase presents in sprouting grain or by fungal amylase. · The resulting dextrose is fermented to ethanol with the aid of yeast producing CO2 as co-product. A second co-product of unfermented starch‚ fiber‚ protein and ash known as distillers grain (a high protein cattle feed) is also produced. Cellulosic

Biology Enzymes IA Design Introduction: Enzymes are globular proteins‚ they are responsible for most of the chemical activities of a living organism. They act as catalysts‚ substances that affects the reaction of other substances without being destroyed or altered during the process. They are extremely efficient in the body system of living organisms‚ one enzyme may catalyse over a thousand chemical reactions every second. But there are certain conditions that need to be fulfilled in order for the

calcium. First the sandwich is chewed with our teeth; the incisor teeth and canine teeth bite it into chunks. The premolar and molar’s grind the chunks of food into much smaller pieces. Saliva’s produced that helps the food become a paste. Here‚ the amylase enzymes turn the starch molecules (from the bread) into maltose – which is used by cells to give us energy. The bolus (lumps of food) squeezes past the epiglottis then down the oesophagus which connects the throat to the stomach. The bolus then

further. This is also the place where ingestion takes place” “What are enzymes” “Enzymes are very efficient catalysts for biochemical reactions. In the mouth there’s an enzyme that will help your food undergo chemical digestion” “What is it” “It is amylase. Which help digest starch into smaller molecules. This enzyme will help break down the bread since it is filled of carbohydrates. Next the food will go down the the pharynx.”

In this assignment I will explain the physiology of two named body systems in relation to energy metabolism in the body. I will be explaining two body systems these are Respiratory system and Digestive system. Energy According to Wright (2007)‚ we need energy for everything we do. Energy can be found in different forms including chemical energy‚ electrical energy‚ thermal energy‚ radiant energy‚ mechanical energy and nuclear energy. We use energy all the time including when we are sleeping. We
