Enzymes are another type of protein, and these molecules catalyze the biochemical reactions that occur in cells. Yet other proteins work as monitors, changing their shape and activity in response ...

However, at high temperatures the rate decreases again because the enzyme becomes denatured and can no longer function. This is shown in the graph below. In the graph above, as the pH increases so ...

Enzymes are proteins that can change shape and therefore become active or inactive. An activator molecule (green pentagon) can bind to an enzyme (light green puzzle shape) and change its overall ...
