What is the effect of pH and temperature on enzyme action?
What is the effect of pH and temperature on enzyme action?
- pH affects the speed of enzyme action, but temperature does not
- Temperature affects enzyme shape, while pH affects enzyme concentration
- pH and temperature can alter the shape of the enzyme, affecting its function (correct)
- pH and temperature have no impact on enzyme action
