What would happen to an enzyme if the temperature and ph changed significantly beyond the enzymes optimum level

At low temperatures, enzyme reactions are slow. They speed up as the temperature rises until an optimum temperature is reached. After this point the reaction will slow down and eventually stop.

 enzyme activity increases steadily between 0 ºC and 40 ºC. It peaks at 40 ºC (the enzyme's optimum temperature) then decreases rapidly.

Different enzymes work best at different pH values, their optimum pH. Many enzymes work fastest in neutral conditions. Making the solution more acidic or alkaline will slow the reaction down. At extremes of pH the reaction will stop altogether.

Some enzymes, such as those used in digestion, are adapted to work faster in unusual pH conditions. For example, stomach enzymes have an optimum pH of 2, which is very acidic.

 enzyme activity increases between pH 4.5 and pH 8. It peaks at pH 8, then decreases.

answer; ///i believe its: ///(embolus);

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
