Optimum pH of most enzymes is 7. Optimum pH is pH at which enzyme shows maximum activity .
It all depends to the particular enzyme you are talking about, there is no general rule. for example in human pepsin catalyse the reaction at high acidic pH (1.5 to 3) whereas trypsin has optimum pH falls between 7 to 9 (neutral to basic).
Optimum in general means the best level of some variable to promote some reaction. In other words, it doesn't mean the highest or biggest or strongest amount of a thing. So I might ask: What is the optimum daytime temperature for growing tomatoes? It is going to be a temperature level or range that is probably also comfortable for people. If I ask: What is the optimum winter daytime temperature for the over-all wellbeing of polar bears? The answer will probably be different. Both are optimum for the situation involved. pH level covers a large range; various levels will be optimum for the growth of various organisms, or for various reactions to occur.
Lets take the example of enzymes. An enzymes optimum pH is the pH that the enzyme/s work best at (its ideal pH).
All enzymes work at their maximum rate at a narrow range of pH ,called as the optimum pH.
its just the max pH at whch a substance(eg.enzyme)works effectively..
The optimal pH is the level of acidity and alkalinity the organism should be at to survive. (It is the pH level that is best for the organism)
This dependes on the application and situation.
The neutral point pH 7 is important.
pH7
The optimum pH is neutral, 7.
The optimum pH of lactase is pH = 6.5.
That is a short form of "optimum pH level", the point where an enzyme is most active. The optimum pH value varies greatly from one enzyme to another. Extremely high or low pH generally results in complete loss of activity for most enzymes.
The optimum pH of salivary amylase is 6.8 (slightly acidic).
6
PH 9
The ideal pH for water is perfectly neutral, or a reading of 7.
The optimum pH is 8.8
PH 9
pH7
The optimum pH is neutral, 7.
The optimum pH of lactase is pH = 6.5.
The temperature optimum can be affected by pH if the pH chosen for a particular experiment deviates from the pH optimum for invertase
It depends of the enzyme. For instance. Amylase in the mouth has a higher pH than say pepsin in the stomach.
