curds casein in the stomach
Renin is an enzyme secreted by the kidneys (from specialized cells called the juxtaglomerular aparatus) whose function is to aid in the conversion of angiotensinogen into angiontensinogen II. Renin controls blood pressure by means of extracellular volume mediation and vasoconstriction
What else can I help you with?
What substrate is rennin?
angiotensinogen
How effective would rennin be at 0 degree celsius?
Rennin is very ineffective at 0 degrees. Its optimum temperature which it works in is body temperature (37oC). If the enzyme is heated up to 70 degrees then it will denature and have no effects at all.
What does rennin change milk into?
its all to do with the milk proteins, caseins. the rennin makes them coagulate. you probbably never got any of that, im doing a planning task and its hard.
Casein is converted to caseinogen by active rennin in the presence of?
Casein is converted to caseinogen by active rennin in the presence of calcium ions. Rennin, also known as chymosin, acts on casein in milk to facilitate curd formation, which is essential in cheese production. The calcium ions help stabilize the casein micelles, allowing rennin to effectively cleave the casein protein. This process is key in dairy processing and the creation of various dairy products.
When cheese is made the enzyme called rennin which curdles milk can be isolated from?
Rennin, also known as chymosin, is an enzyme found in the stomach lining of calves. It can be isolated from the stomachs of calves or produced using biotechnology. Rennin is used in cheese making to coagulate milk, separating it into curds and whey.
What is the fucntion of the HCI rennin?
CI rennin?
Where is rennin made?
Type your answer here.how to make rennin
What happens to the enzyme rennin when the temperature is raised to the boiling point?
When the temperature is raised to the boiling point, the enzyme rennin will denature, meaning it will lose its shape and function due to the high heat. This will render the enzyme ineffective in catalyzing reactions.
What is a factor that helps create the stomach mucosal barrier?
rennin
Who discovered rennin?
Robert Tigerstedt in 1898
Should vegetarians eat rennin?
No. Rennin is derived fom rennet, which comes from a cows stomach.
Where is rennin produced?
In the stomach
What substrate is rennin?
angiotensinogen
What would happen to a newborn mammal if its body could not produce rennin?
The function of rennin is to curdle milk proteins by converting the soluble protein caesinogen into the insoluble protein caesinogen. If the new born mammal is unable to produce rennin, then the soluble milk proteins would just pass through the stomach into the duodenum like water. This is bad because the milk proteins would not be able to get digested by the pepsin. However, if there is rennin, the converted insoluble milk proteins would be abe to stay in the stomach long enough for the pepsin to digest it into polypeptides.
Do you expect that optimal PH for pepsin would be the same as that for rennin?
No, optimal pH for pepsin is around 2.0 (acidic environment) while optimal pH for rennin is around 6.5-6.7 (slightly acidic to neutral environment). Each enzyme has a specific pH range at which it functions most efficiently due to its unique structure and function.
What happens to the activity of rennin as it passes from the stomach into the small intestine?
Rennin, an enzyme primarily found in the stomach, plays a crucial role in curdling milk. As the chyme moves from the stomach into the small intestine, the pH increases and becomes less acidic. This change in pH inactivates rennin, reducing its activity, as it is adapted to function optimally in the acidic environment of the stomach. In the small intestine, other enzymes like peptidases take over the digestion of proteins.
What pH does rennin work best?
the optimal pH for rennin is around 1-2, as this closely resembles the acidic environment of the stomach where rennin is most commonly found. However rennin also works at neutral pH, although at a much lower level of reaction. This is necessary because sometimes the stomach is diluted by outside materials.
