What are the factors affecting enzyme activity?

-temperature, pH, substrate+enzyme concentration

1 of 5

Describe and explain a graph for inceasing temperature

-more kinetic energy so molecules move faster=more collisons and formation ofenzyme substrate complexes. At optimin temp hydrogen bonds break changing shape of active site=denatured.

2 of 5

Describe and explain a graph for changes in pH

pH changes cause ionic bonds to break, which changes active site, ezyme becomes denatured

3 of 5

Describe a grpah for substrate and enzyme concentration

if enzymes kept at fixed rate- level of substrate increases results in more enzyme activity, because more substrate to fill available active sites. Rate levels off as enzymes working at maximum rate. Substrate availability at fixed rate- more eni

4 of 5

What is enzyme inhibition and what are the two types?

-lowers enzyme activiy, non-cometitive + competitive
