Research into Enzymes – For Biology Rennin Rennet, substance found in the gastric juices of young milk-drinking mammals. Rennet contains a milk-coagulating enzyme, called rennin or chymosin, the active principle of rennet preparations used in making cheese and junket. Rennet extracts are commercially prepared from the inner lining of the fourth stomach of calves. Enzymes Enzymes are large proteins that speed up chemical reactions. In their globular structure, one or more polypeptide chains

The Effect of Temperature on the Activity of Rennin in Milk Aim: To find out what effect different temperatures have on the enzyme, rennin, in milk. Introduction An enzyme is a biological catalyst. It speeds up a reaction by lowering the activation energy required to start the reaction. It speeds up a reaction, but remains unchanged unless certain limiting factors are introduced. It is composed of polymers of amino acids. An enzyme has an optimum pH and temperature. When an enzyme

Varying Concentration of Rennin and Its Effect on the Goagulation Time of Milk Scientific Knowledge Enzymes Enzymes are large molecules, which are protein in nature. They are biological catalysts that speed up chemical reactions in the body. They operate by a "lock and key" method. The Enzyme has a certain "lock" (active site) that only a specified substrates "key" will fit into. Enzyme action Rennin A proteolytic enzyme that speeds up the coagulation of milk. It is usually

Rennin – A Proteolytic Enzyme Major Discussion:  Role of rennin in helping young mammals digest milk  Role of rennin as an industrial catalyst to make cheese Proteolytic Enzyme: Any group enzymes that catalyze the hydrolytic degradation of proteins or polypeptides to smaller amino acids polymer is called proteolytic enzyme. Rennin is a proteolytic enzyme made by chief cells in the stomach. Rennin also known as “Chymosin”. Rennin enzyme plays an important role in helping young mammal digest milk

rennet, my partner and I decided upon the first option. We made this decision as we felt it would be valuable to our scientific knowledge if we had a better understanding of how different temperatures can effect the behaviour of an enzyme, such as Rennin, which is also known as Chymosin. Our scientific knowledge tells us that enzymes work most efficiently at specific temperatures, and this experiment helps us to discover exactly which temperatures they are. It is important to remember that the

Biology Experiment Prediction The temperature I thought the experiment would work best at is 37 c. I think this because your body temperature is 37oC and it is same as cows. Rennin is from a cow and that is what we used. Rennin is an enzyme and it is affected by temperature. Theory The lock and key theoryis simply a way of describing how specific an enzyme is for its substrate. Just like a lock requires a specifically shaped key for it to work so does an enzyme. Each enzyme is a

curds formed, I concluded that specimens Ca and Cb also cannot perform the process of proteolysis. My conclusion is supported by the fact that there was no clearing of the medium. I have also determine that neither of my organisms can make the enzymes rennin, proteolytic or even proteases. I know my specimens cannot produce proteases due to the fact that there was no blue coloring in the tubes which means that the byproduct Ammonia was not produced to increase the pH. Since neither of my specimens can

Cheesemaking is an ancient and constantly evolving practice that, despite its humble origins, is deeply rooted in science of all kinds. The practice of cheesemaking is widely believed to have begun some time between 6000-7000 BC, and has been seen to spread across cultures throughout the world. Cheese is not a specific term; it is the generic name for fermented milk-based food products, which are nearly endless in variety. Although there is no official number of cheese types in the world, the number

the development of cardiovascular diseases including stroke and may also have a role in the development of vascular cognitive impairment and vascular dementia [1, 2]. Angiotensin I-converting enzyme (EC 3.4.15.1; ACE) plays an important role in the rennin-angiotensin system and it is a carboxyl-terminal dipeptidyl exopeptidase that catalyzes the conversion of angiotensin I to angiotensin II [3-6]. ACE converts an inactive form of decapeptide, angiotensin I, to a potent vasoconstrictor, octapeptide

Hypertension is a condition, where the force of blood pumping through body is high enough for it to cause internal damage. High blood pressure is determined by measuring the force of the blood against the blood in your arteries and the amount of resistance with the arteries. Blood pressure is measured by sphygmomanometer, this device measures the systolic and diastolic pressures in the arteries. The systolic is the top the number in blood pressure which should be around 120. While the diastolic is
