varies greatly. some bateria in acidic hotsprings like those in yellow stone live in pH 1 and so contain proteins adapted to these low pH's conversely some bacteria can live in very high alkaline pH. Even in the human body proteins each have a slightly different pH range at which they are stable most it is around 7.4.
What else can I help you with?
What is a change in this can denature a protein?
Temperature, pH, organic solvent, mechanical forces
What is the optimum pH for tyrosinase?
The optimum pH for tyrosinase activity is typically around pH 6.5 to 7.5. This enzyme functions best in slightly acidic to neutral conditions. Extremes in pH levels can denature the enzyme and reduce its activity.
What happens to an enzyme-substrate reaction when the enzyme has been subjected to heat or high-low pH?
When an enzyme is subjected to heat or extreme pH levels, it can denature, losing its specific shape and functionality. This can affect the enzyme's ability to bind to the substrate and catalyze the reaction efficiently. In extreme cases, the enzyme may become permanently inactivated.
What are the two factors that effect the efficiency of an enzyme?
Two factors that affect the efficiency of an enzyme are temperature and pH. Enzymes work best within a specific temperature and pH range, and deviations from these optimal conditions can denature the enzyme leading to decreased efficiency. Additionally, substrate concentration plays a role in enzyme efficiency as higher substrate concentrations can lead to faster reaction rates until all enzyme active sites are saturated.
What effect does temp and pH have on enzymes?
enzymes require specific temperature and pH in order to work properly. Otherwise, the temperature or pH change their conformation or disable their ability to bind the substrate because the required electrostatic interactions might not happen under different pH.
How does pH levels effect an enzyme?
Changes in pH levels can alter the shape and charge of the active site of an enzyme, affecting its ability to bind with the substrate. This can either enhance or inhibit enzymatic activity, depending on the specific enzyme and its optimal pH range. Extreme pH levels can denature the enzyme, rendering it inactive.
Can the active site of an enzyme be damaged at very high pH levels?
The active site of an enzyme can very much be influenced and damaged by a very high pH level. An enzyme is a protein, and because of that it is very sensitive to pH levels. High pH can denature a protein, and thus "damage" the active site.

The optimum pH for tyrosinase activity is typically around pH 6.5 to 7.5. This enzyme functions best in slightly acidic to neutral conditions. Extremes in pH levels can denature the enzyme and reduce its activity.
Does amylase work at pH levels other than the optimal pH?
Yes, amylase can still work at pH levels other than its optimal pH, but its activity might decrease. Extreme pH levels can denature the enzyme, affecting its ability to function properly.
Enzymes are affected by both pH and?
Enzymes are affected by both pH and temperature. Changes in pH can alter the shape and charge distribution of the enzyme, affecting its ability to bind to substrate molecules and catalyze reactions. Extreme pH levels can denature the enzyme and render it nonfunctional.
Explain the effects of pH on enzyme reaction rates?
Enzyme reaction rates are influenced by pH because enzymes have an optimal pH at which they function most effectively. Deviation from this optimal pH can denature the enzyme, rendering it less active or inactive. pH affects the enzyme's shape and charge, which in turn affects its ability to bind to the substrate and catalyze the reaction.
What are the factors of denature enzymes?
Factors that can denature enzymes include high temperatures, extreme pH levels, and exposure to certain chemicals or solvents. These conditions can disrupt the shape and structure of the enzyme, leading to loss of its function.

How does pH affect enzyme functions?
Enzymes lower the amount of Activation Energy needed for a chemical reaction, therefore speeding up the chemical reaction. For an enzyme to do this it needs to be at the correct pH, salinity, and temperature otherwise the enzyme will not be able to work. When an enzyme is in a pH that is not suitable, the enzyme's shape and structure alter and make it unable to speed up a reaction.
What effect does temp and pH have on enzymes?
enzymes require specific temperature and pH in order to work properly. Otherwise, the temperature or pH change their conformation or disable their ability to bind the substrate because the required electrostatic interactions might not happen under different pH.
