What pH does salivary amylase function best?
The optimum pH of salivary amylase is 6.8 (slightly acidic).
Where does amylase act in humans?
Amylase is produced by the salivary glands and works in the mouth to break down chardohydrates(digests starch into maltose). It only works for a short amount of time because when you swallow the food it is inhibated by the acid in the stomach. Amylase works best at a pH of 7.
What type of environment do cells function best?
Isotonic
What is the effect of temperature on salivary amalyse activity?
Every enzyme has a temperature range of optimum activity. Outside that temperature range the enzyme is rendered inactive and is said to be totally inhibited. This occurs because as the temperature changes this supplies enough energy to break some of the intramolecular attractions between polar groups (Hydrogen bonding, dipole-dipole attractions) as well as the Hydrophobic forces between non-polar groups within the protein structure. When these forces are disturbed and changed, this causes a change in the secondary and tertiary levels of protein structure, and the active site is altered in its conformation beyond its ability to accomodate the substrate molecules it was intended to catalyze. Most enzymes (and there are hundreds within the human organism) within the human cells will shut down at a body temperature below a certain value which varies according to each individual. This can happen if body temperature gets too low (hypothermia) or too high (hyperthermia).
What are 2 examples of enzymes and the pH of the environment in which it works?
Two examples of enzymes are pepsin and amylase. Pepsin, which is involved in protein digestion, functions optimally in the acidic environment of the stomach, with a pH around 1.5 to 2.5. Amylase, on the other hand, facilitates the breakdown of starches into sugars and works best in a neutral to slightly alkaline environment, with an optimal pH around 6.7 to 7.0, as found in the mouth and small intestine.
What pH does salivary amylase function best?
The optimum pH of salivary amylase is 6.8 (slightly acidic).
What pH does it acts salivary amylase works best in?
About 7.4 pH.
Does acid and base pH value has salivary amylase stops?
Yes,amylase work best in neutralized medium.

Does amylase work in acid or alkali?
Amylase works best in a slightly alkaline environment, with an optimum pH range of 6.7 to 7.0. It can also function in slightly acidic conditions, but its activity decreases as pH deviates from the optimum range.
In what environment does amylase work best at an alkaline environment or an acidic environment?
It works best in an alkaline environment. I can't think of why just yetthough! I'll come back to you on that one, I'll have to do some research! :D
Why does amylase work in the mouth but not the stomach?
Because of enzyme specificity, enzymes require certain temperatures and pH's to work. Now I don't think there is a temperature change, but there is most certainly a pH change as the mouth has a near neutral pH while the stomach has a more acidic pH of about 2-3.
Describe the action of salivary amylase?
Salivary amylase is an enzyme found in saliva that begins the breakdown of carbohydrates in food by breaking down starch into smaller sugars like maltose. It works best in a slightly acidic environment (pH 6.7-7.4). The enzyme continues to work in the mouth and is eventually inactivated by the acidic environment of the stomach.
What are the best conditions in pH for amylase protese and lipase?
Amylase has an optimal pH range of 6.7 - 7.0 and an optimal temperature of around 37 degrees Celsius or 98.6 degrees Fahrenheit. This is what would be expected of an enzyme that needs to be in its most active form in the saliva of the mouth.
What is the optimum temperature for salivary amylase activity?
The optimum temperature for salivary amylase activity is around 37 degrees Celsius, which is the normal body temperature for humans. This is the temperature at which salivary amylase functions most efficiently in breaking down carbohydrates into simpler sugars. Deviations from this temperature can result in decreased enzyme activity.
What type of environment do cells function best?
