This type of inhibition blocks the active site of an enzyme:

• competitive inhibition

• allosteric inhibition

• noncompetitive inhibition

A molecule that is so similar to the normal substrate that it competes for the active site of the enzyme

• Allosteric Inhibition

• Competitive Inhibition

• Noncompetitive Inhibition

• Feedback Inhibition

The process illustrated in the figure is called:

• condensation

• protein synthesis

• hydrolysis

• dehydration synthesis

Which of the following requires the dehydration reaction of two amino acids?
