When the pH level rises, the enzyme's bonds become weakened, changing the enzyme's structure and disabling its function (so its substrates can't enter its active site).
Enzymes, like all proteins, are folded into three-dimensional shapes (called tertiary structure). Their structures are determined by their amino acid sequences and the conditions of the solution they're in. The acidity of a solution can affect the tertiary structure of the protein, making it more or less accessible to the substrates or ligands(molecules that affect enzyme activity but are not processed by the enzyme).
In most cells, enzymes acting in the cytosol and mitochondria have pH optima of around 7.2 (physiological pH). However, some enzymes in these compartments actually work better at lower pH, which occurs when the cells are stressed. The vacuole and apoplastic space (between plasma membrane and cell wall) of plant cells is much more acidic, therefore enzymes acting there have pH optima between 3-5. In the human digestive tract, there are enzymes operating at basic pH (mouth and intestine) and highly acidic pH (stomach).
So the effect of pH depends on the "native" conditions that the enzyme is optimized to use.
pH is the degree of acidity or alkalinity. Each enzyme is different. They tend to work at the optimum pH level of the environment in which they are found. Enzymes do not have pH, but are influenced by pH, which is a property of the solution in which the enzymes work. A change in pH will affect the shape and/or the electrical charge of an enzyme and/or the substrate. This will alter the enzyme's ability to perform its activity, which basically means it won't be able to allow the substrate to bind to its active site and undergo catalysis.
As you may know, the pH level is how acidic or alkaline an environment is. Certain enzymes, for example salivary amylase in the mouth, work best at a certain pH level. If the pH level is too high or low, then the enzymes will either slow down and be rendered useless, or decompose.
If the pH is higher it is more basic so it can hinder the enyzmes reaction rate, however if the pH is lower, its more acidic and will increase the reaction rate of the enzymes.
Ph level, enzyme concentration, substrate concentration etc
Temperature and ph level.
Enzymes are quite easy to break.So if the pH is too acidic,then the enzyme might break.Therefore if the temperature is too high,the enzyme will also break.
It will affect the shape and lead to reduced activity.
The activity of an enzyme is affected by temperature, pH and the concentration of the substrate.
Ph level, enzyme concentration, substrate concentration etc
yeh it can
you can say enzyme reaction depends on ph, temp
Temperature and ph level.
The pH is varied to effect, by its affect, this test.
pH and Temperature both impact the enzyme's function.What_factors_affect_enzyme_production
Substance concentration, enzyme concentration, temperature and PH level
Mostly pH, Temperature, and salt.
Temperature, pH, salt concentration
Enzymes operate best under a tight, optimal range of pH values. Extreme pH can seriously affect enzyme activity, so it is little wonder that big changes in pH can slow down enzyme activity. Extreme changes can often irreversibly inactivate and denature an enzyme.
Ph level accelerates enzymes and temperature slows the process down
pH, temperature, substrate concentration and enzyme concentration influences the rate of reaction
