Enzymes- 2

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

A receptor site that a molecule can bind to that changes the shape of the active site is called a(n):

• Allosteric Site

• Active Site

• DiSulphide Bridge

• MHC Receptor

Molecules that bind to enzymes and enhance an enzyme's ability are called:

• CoFactors

• CoEnzymes

• Allosteric Inhibitors

• Allosteric Activators

Organic molecules that temporarily bind to enzymes and enhance an enzyme's ability are called:

• CoFactors

• CoEnzymes

• Allosteric Inhibitors

• Allosteric Activators

When an enzyme tightens around a substrate, this is called:

• An awkward hug

• Induced fit

• Competitive Inhibition

• Non competitive Inhibition

What's going on in this picture?

• The enzyme is taking the red substrate and turning it blue

• The enzyme's active site is blocked by a competitive inhibitor

• The enzyme can't function if too many substrates are trying to bind

• This is an example of an anabolic enzyme reaction

Blocking Active site of an enzyme

• competitive inhibition

• allosteric inhibition

Enzymes in your body probably work best at which of the following temperatures>

• 25^oC

• 98^oC

• 37^oC

• 210^oC

Which is true of non-competitive inhibition?

• It is irreversible

• The inhibitor binds only to the active site of enzyme

• The inhibitor binds to enzyme to lower activation energy

• It can be reduced by increasing the concentration of the substrate

Which type of reversible enzyme inhibitor binds to both the free enzyme and the enzyme-substrate complex?

• Non-competitive inhibitor

• End product inhibitor

• Competitive inhibitor

• None of the above
