3.  Based on the graph, how do enzymes affect chemical reactions?

• Enzymes do NOT affect chemical reactions.

• Enzymes are proteins that slow down chemical reactions

• When enzymes are NOT present the speed of the chemical reaction increases.

• Enzymes are proteins that speed up chemical reactions.

4. What claim best supports the data in the graph?

• Enzymes help our bodies function by speeding up chemical reactions

• Enzymes love the cold!

• Hot temperatures can decrease enzyme activity.

• Enzymes are not affected by temperature.

5.  What statement of evidence best supports the claim?

• enzyme activity is very low at temperatures between 0-12oC.

• enzyme activity is very low at temperatures over 40oC.

• enzyme activity is the greatest at temperatures over 40oC.

• enzymes love to be in temperatures between 13-25oC.

6.  What statement of reasoning best supports the claim and evidence?

• Freezing enzymes is the best thing to do to increase their activity.

• Acid solutions can damage enzymes and slow down their activity.

• The human body temperature must remain stable to support enzyme activity

• Hot temperatures can denature enzymes and slow down or even stop their activity.
