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

Which of the following correctly describes enzyme structure and function?

• The shape of an enzyme is responsible for its function.

• All enzymes can bind to all substrates.

• The substrate is responsible for the shape of the enzyme.

• The location of an enzyme determines its function.

Blocking Active site of an enzyme

• competitive inhibition
• allosteric inhibition

When a molecule can occupy the same active site as the substrate, a situation called __________________ can result

• Competitive lnhibition
• Allosteric Regulation
• Non-Competitive Inhibition
• Feedback Inhibition

When you have a severe fever, what grave consequence may occur if the fever is not controlled?

• destruction of your enzymes' primary structure

• removal of amine groups from your proteins

• change in the tertiary structure of your enzymes

• removal of the amino acids in the active sites of your enzymes
