1. Enzyme Reaction Rates -enzymes are also known as biological catalysts
-a catalyst is a substance that speeds up chemical reactions

2. Enzyme Reaction Rates -Several factors affect how fast enzymes work:
-These include pH, temperature, and
concentration pH
-Enzymes work within a limited pH range

3. Enzyme Reaction Rates Temperature
-Increasing temperature can increase enzyme reactions rates up to a point
-Anything beyond the optimal temperature will slow enzyme reaction rates even to the point of denaturing (or destroying) the enzyme

4. Enzyme Reaction Rates Concentration
-Increasing the concentration increases reaction rates up to a certain point and then it will make no difference in terms of how much more is added

5. Enzyme Analysis
1. What is the optimal temperature for the “blue,” “red,” and “green” enzymes?
2. Why do you think adding more substrate seems to make less of a difference after a certain point?
