An enzyme speeds up a chemical reaction in the cell but can only be used once.  True or False? 

• true
• false

Which of the following conclusions can be drawn from this graph?

• The optimum pH of the enzyme is 6.6.
  
• The optimum pH of the enzyme is 5.8
  
• The enzyme’s activity increases as pH increases 5.0 to 9.0
  
• The enzyme’s activity is greater around pH of 8.0 .
  

Changes in pH and temperature can ___________________ an enzyme which causes it to lose its shape and affects its function.

• puncture

• denature

• double

Organisms living in a bog environment must be able to tolerate nitrogen-poor acidic conditions. Bog plants such as the Venus flytrap and sundew are able to obtain their nitrogen by attacking and consuming insects. These plants produce chemicals that break down the insects into usable compounds.

These chemicals present in the bog plants that break down the insects mentioned in the reading passage are most likely...

• hormones

• lipids

• enzymes

• carbohydrates

Based on the graph, what is the optimal temperature for this enzyme?
