Amylase

produce more salivary amylase(It is the key factor in the decomposition of starch in food). Most modern humans have several code that is copies of the amylase gene, AMY1. Modern hunters have only a little bit of the copies of the amylase gene no matter where they come from. (They are not similar to the descendants of the ancient farmers.) This shows that our ancestors have the more and more strong adaptability for the food, and they no longer need a large amount of salivary amylase to digest…

Introduction: The purpose of the tests (culture media, motility, enzymes, etc.) we preform on the numerous bacteria in lab is to show any biological or chemical characteristics of the bacteria that may help it survive or adapt in the wild, how it may be useful or hazardous to humans, and use as general knowledge to differentiate bacteria from each other. In the Culture Media test we can use solid and liquid media to grow multiple bacteria in lab. It can help us determine what processes the…

first process is Mastication. This is the biting and chewing a feed breaking food into smaller particles. The incisor teeth cut and the molars grind. The food is mixed with saliva causing a breakdown of digestion of carbohydrates begins in the mouth, amylase is secreted and starts breaking down the carbs in the bread to form a bolus of food. This Bolus of food is pushed between the hard palate and the tongue mixing the bolus of food with saliva and pushing the bolus of food from the mouth into…

this lab was to observe the effect of the enzyme concentration versus the reaction time of an enzymatic reaction, and the effects of the reactants and products concentration direction of the reaction. Specifically, in this lab the enzymes salivary amylase and phosphorylase were looked at the effect of the enzyme concentration versus the reaction time of an enzymatic reaction were observed by the iodine test along with the benedict’s test. Enzymes are known as biological molecules which catalyze…

when it receives the food and contains salivary amylase; this begins the digestion of carbohydrates as well as lubricating the mouth and helping the formation of the bolus. The taste buds on the tongue provide unusual sensations of tasting the food and the oral cavity also plays a vital part in speech and other body processes. Movement inside the oral cavity begins when the food begins to be chewed up by the teeth, this then starts to form the bolus. Next, swallowing begins. Swallowing starts…

contains enzyme called amylase, which breaks down starch. In the mouth the Meat patty and the bread could be broken down and digested. Step 2. The oesophagus has two layers. Its interior is lined with cells that are packed very closely together creating a smooth surface. The circular muscle around the outside of the oesophagus is also smooth. Your swallow forces the food toward the stomach. Step 3. Once it reaches your stomach the cheeseburger is broken down even more, the amylase that went…

found that enzymes break down starch into maltose, break complex sugars into simple sugars, and break protein chains (this can happen without the help enzymes.) Amylase is the first enzyme that takes action in the dough of bread. Amylase acts on starch (amylose or amylopectin), breaking the starch chain between adjacent sugar rings. Amylases, which are found in flour, are mobilized when water is added. When yeast encounters a maltose, it absorbs it. The enzyme maltase bonds to the maltose and…

the chemical digestion of food in the mouth because it contains various enzymes which help catalyze and speed up the breakdown of the macronutrients into their simpler components. Carbohydrates are broken down via the enzyme salivary amylase. More specifically, amylase breaks down starch (a polysaccharide) which is made up of amylose and amylopectin into smaller starch units known as disaccharides and monosaccharides. Very…

enable the substrate and the active site to fit precisely. The enzymes-substrate undergoes internal arrangement that forms a product. Finally, the enzyme releases the product as an end reaction. An example of this would be salivary amylase and starch. The salivary amylase bonds with starch in the mouth, then the chemical bonds are broken down to form simple sugars which are the end product of this reaction.…

Enzymes are biological catalysts that speed up chemical reactions and are inexhaustible. They can increase the rate at which reactions occur by up to a factor of 10^19. The material that is being acted on by the enzyme is called a substrate. Enzymes work because they can bind to the transition state better than the substrate, which lowers the activation energy causing the speed of a reaction to accelerate. The enzyme combines with a substrate at the enzymes active site which creates the enzyme…
