4.8
Most cells operate around a pH of 7.4
Enzyme become denatured.
The most important factor in determining a protein's optimum pH level is its specific amino acid composition.
The optimum pH for most elastases is around 8.0 to 9.0. Elastases are enzymes that break down elastin in the extracellular matrix of tissues, and they function best within this pH range. Deviation from this pH range can significantly impact the enzyme activity.
The optimum pH is neutral, 7.
I believe it's 7.3, the pH of human blood, as most enzymatic reactions occur there. However, there are special enzymes, such as the ones which are in the stomach, which work best at around a pH of 2.
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
To determine the optimum pH of an enzyme, you can conduct experiments at different pH levels and measure the enzyme activity. The pH at which the enzyme shows the highest activity is considered its optimum pH.
When the pH is not at its optimum, then the differing pHs will disrupt the bonding between the R groups of the amino acid. This will change its shape, altering the shape of the activation site. Within an acceptable pH range, the enzyme will continue to function but since the shape of the activation site has been slightly altered, the reactions won't be able to proceed as quickly as they could at the optimum pH. The further away from the optimum pH, the more the shape of the activation site will change. Eventually, the substrate won't fit into the activation site and the reaction will stop.
The optimum pH for what? Please provide more context so I can give you an accurate answer.
optimum pH of amylase from sweet potato is about 6.0
