Enzyme Inhibition

Front

At high temperatures enzyme activity declines because of:

Back

Denaturation

Front

At low temperatures enzyme activity declines because of: Denaturation, Decreased Kinetic Motion, Increased H-Bonding, Dissociation of Ionic Compounds

Back

Decreased Kinetic Motion

Front

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

Back

Competitive inhibition

Front

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

Back

Allosteric Site

Front

A molecule binds to an enzyme and opens the active site so it can bind to the substrate. This is called:

Back

Allosteric Activation

Front

A molecule binds to an enzyme and decreases the ability of the active site to bind to the substrate. This is called:

Back

Allosteric Inhibition

Front

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

Back

CoFactors

Front

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

Back

CoEnzymes

Front

Which explanation best fits the graph for pH's effect on an enzyme? Options: As the pH gets closer to neutral more H-Bonds are broken, Larger numbers of H+ & OH- ions distort the active site, There are more collisions between substrates and active sites near the optimal pH, Low pHs cause more H-Bonds to happen near the active site

Back

Larger numbers of H+ & OH- ions distort the active site

Front

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

Back

Induced fit
