No, the optimum pH for an enzyme depends on the environment in which it normally works. Your stomach is an acidic environment which contains an enzyme called pepsin. This not only works better in acid environments but actually denatures (that is, totally stops working) if the pH rises above 5.0.

All enzymes act best at a pH close neutral?
This is not true. Different enzymes thrive in completely different pH conditions. Consider the protease pepsin, which works in the stomach. It breaks down proteins in acidities as low as pH 2. In the duodenum, lipase works best in slightly alkaline conditions.
Are Enzymes are able to work at any temperature?
up to a point. All chemical reactions work faster at higher temps, but enzymes come apart at high temps. human enzymes (protiens) start to cook at about 106 to 108 degrees.
Are all proteins enzymes Explain your answer?
No. All enzymes are proteins but not all proteins are enzymes. Muscle tissue is made of protein but it is not made of enzymes.
Do humans have any enzymes in bodies?
Yes. All life on this planet has enzymes. Enzymes are protein molecules that act to catalysts to perform the chemical work required by cells to function. They allow cells to grow, reproduce and use energy. Exactly WHICH enzymes are present in any given organism is dependent on the organism. Plants will have different enzymes than animals or fungi or bacteria, but ALL life has enzymes.
Are enzymes composed mostly of proteins?
Most enzymes are protein, but not all protein are enzymes.
How can enzymes be inactived?
All enzymes work best at a certain temperature and pH. They also need a substrate to work on. A change in pH or temperature will inactive it by denaturing it. If the substrate is very low in quantity or is absent, the enzyme will be inactive.

Enzymes work by what-?
Enzymes work by reducing the energy of activation.
Does all enzymes work well on every temperature?
Far from it. Most enzymes only work well in a characteristic, rather narrow range of temperatures.
If all enzymes are proteins but all proteins are not enzymes then what makes enzymes different fr?
Enzymes are proteins, but as you can imagine, different parts of the body need different types of enzymes to work efficiently. Can you imagine the enzymes which break down food in the process of digestion being replaced by the enzymes which assist respiration or photosynthesis? It wouldn't work. Each type of enzyme controls different chemical processes.
Why do all digestive enzymes not work on all groups of food?
takes place in the mouth
Why are all enzymes catalysts but not all catalysts are enzymes?
but all catalysts aren't enzymes...
Why are all enzymes are catalysts but not all catalysts are enzymes?

Do enzymes work only on single substrate in most cases?
Yes, almost all work on a single substrate.
When does it mean when an enzyme is denatured?
when an enzyme is denatured, it means that it is unable to be functional or active. for example, the enzymes in a flower for it to use photosynthesis work best at around 35 degrees celsius. once the temperature reaches past 60, the enzymes stopp working and the plant no longer is able to produce photosynthesis. denature all in all, denatured is when the enzyme is unable to work
What are optimal conditions of enzymes?
every enzyme has specific optimum temperatures and pH. 1. The pH is very specific even a minor change of .5 will cause the enzyme to denature. 2. The temperature is less specific all enzymes will work below the optimum temperature but the reaction will be slower. Above the optimum temperature the enzyme will denature. Note the optimum temperature of the human body is around 37.5 degrees C and the optimum pH is around 7.3.
