Temperature, pH, substrate concentration
Boiling usually destroys enzymes.
No, enzymes do not require ATP for their catalytic activity.
Enzymes are biological catalysts that speed up chemical reactions in living organisms, and their activity can be significantly affected by salinity. High salinity can lead to changes in enzyme conformation and stability, potentially reducing their activity or causing denaturation. Conversely, some enzymes are adapted to function optimally in saline environments, such as those found in marine organisms. Therefore, the effect of salinity on enzymes varies depending on the specific enzyme and the organism's adaptation to its environment.

It has no effect
Cold temperatures can slow down enzyme activity by decreasing the kinetic energy of molecules, leading to fewer molecular collisions and reduced enzyme-substrate interactions. This can affect the rate of chemical reactions catalyzed by enzymes, as they typically have an optimal temperature range for activity. Ultimately, prolonged exposure to extreme cold temperatures can denature enzymes and render them nonfunctional.
what i know is enzymes are denatured in organic solvents loosing their activity.

temperature and pH
not a thing
Hydrochloric acid can denature enzymes by disrupting their structure and altering their active site. This can impact the enzyme's ability to catalyze chemical reactions effectively, potentially leading to a decrease or loss of enzyme activity.
Temperature significantly affects the activity of lactose enzymes in bacterial cells. Generally, as temperature increases, enzyme activity rises due to enhanced molecular movement, up to an optimal temperature where the enzyme functions best. Beyond this optimal point, high temperatures can lead to denaturation of the enzyme, causing a loss of activity. Therefore, maintaining an appropriate temperature is crucial for optimal lactose enzymatic activity in bacteria.
