What is the optimum PH of lactase catalyzed reaction?
The optimum pH of lactase is pH = 6.5.
What is the optimum temperature for enzyme activity in the body?
37.5 degree Celsius
What is the optimum temperature for pepsin activity in Celsius?
According to Biologists, the optimum temperature for pepsin ranges from 37 degrees Celsius to 42 degrees Celsius which are perfect human body temperatures.
What affect does temperature have on cellular enzyme activity?
Enzymes generally work within a given temperature range. As the temperature is increased the activity will increase. However if the optimum temperature is surpassed, the enzymes will stop working.
How can an enzyme be denatured and why does that process result in the loss of activity of the enzyme?
by increasing the temperature above the optimum temperature(above 45), we can denature an enzyme!! the temperature affects the non-covalent bonds of an enzyme!! at 40
What is the optimum PH of lactase catalyzed reaction?
The optimum pH of lactase is pH = 6.5.
Optimum temperature of pepsin?
The optimum temperature for pepsin is between 30 degrees Celsius and 40 degrees Celsius. Activity has been reported outside of this range.
What can a fever slow down?
enzymes best function at optimum temperature for human body optimum temperature is 37 C, raise in optimum temperature affects the function of enzymes and with very high temperature enzyme activity ceases. high temperature also affects proteins resulting in protein structural changes. fever slow down the enzyme activity.
How may enzymes be deactivated?
high temperature may denature enzyme activity by passing optimum temperature
What does your data indicate about the optimum level for this lactase catalyzed reaction?
PH 9
What is the optimum temperature for enzyme activity in the body?
37.5 degree Celsius
What is the optimum temperature for pepsin activity in Celsius?
According to Biologists, the optimum temperature for pepsin ranges from 37 degrees Celsius to 42 degrees Celsius which are perfect human body temperatures.
What are the optimum temperature and the optimum pH of an enzyme?
Every enzyme works at its maximum rate at a specific temprature called as optimum temprature for that enzyme. AND all enzymes work at their maximum rate at narrow range of pH, called as optimum pH. A slight increase or decrease in pH causes the retardation in enzyme activity or blocks it completely.
What are the effects temperature and pH level have in the efficacy of digestive enzymes?
As you increase the temperature at first the activity of an enzymes will also increase, so the reaction will go faster. At a certain temperature, called the optimum temperature, the enzyme will work at its maximum rate. Above the optimum temperature the enzyme activity decreases. This is due to the loss of shape by the enzyme molecules, a process called denaturation. In mammals, most enzyme shave an optimum temperature of about 37 oC. Roughly speaking, the rate of an enzyme reaction doubles for each 10 oC rise in temperature, until the optimum temperature is reached. pH affects enzymes in a similar way. At a low pH many enzymes have a low activity. As the pH increases the enzyme activity increases until the optimum pH at which the enzyme has maximum activity. Above this pH enzyme activity decreases. These effects are also dueto denaturation of the enzyme molecules at extreme pH values. Many enzymes work best at around pH 7.0. An important exception is pepsin, a protein-digesting (protease) enzyme in the stomach. This works at low pH values such as those found in the stomach (around pH 2.0), due to the presence of hydrochloric acid.
What does optimum temperature mean?
Optimum temperature is the temperature at which the system can take at its most efficient.
How does temperature affects activity?
The enzyme activity increases as the temperature rises due to the substrates colliding with the enzymes' active sites more frequently at higher temperatures. However, each enzyme has an optimum temperature as high temperatures denature enzymes.
What affect does temperature have on cellular enzyme activity?
Enzymes generally work within a given temperature range. As the temperature is increased the activity will increase. However if the optimum temperature is surpassed, the enzymes will stop working.
