Enzyme Function

Enzymes are considered to be 

• Lipids
• Carbohydrate
• Protein
• Nucleic Acid

What is the purpose of an enzyme?

• give permission for the biochemical reaction

• raise activation energy

• speed up biochemical reactions

• control how many reactions occur

Where do substrates bind on an enzyme?

• voltage-gated channels
• surface receptor
• calcium channels
• active site

Which of the following tasks listed below is most associated with enzymes?

• catalyze chemical reactions                  
• store genetic information       
• store chemical energy in the cell   
• dissolve nutrients and minerals 

Enzymes are examples of

• biological catalysts

• proteins

• macromolecules

• all of these are true

What is structure A?

• Substrate
• Active site
• Enzyme
• Products

What is the name for the mechanism of normal enzyme activity?

• lock and key

• jigsaw puzzle

• hammer and nail

• competitive inhibition

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 .
  

Normal body temperature is 37 degrees Celsius. At 40 degrees Celsius, your biological enzymes will...

• Function optimally

• Denature (change shape and break down)

• Wait until the temp. increases

• Wait until the temp. decreases

What gives an enzyme substrate specificity?

• Size

• Shape

• Name

• Location it is found in
