Enzyme:Structure-Function-factors

Each enzyme functions best at a specific pH level.

• True (Enzymes have an optimal pH range and can be denatured by extreme pH changes.)

• False (Enzymes can function equally well at any pH level.)

• True (Enzymes are not affected by pH levels.)

• False (All enzymes work best at a neutral pH of 7.)

An enzyme that breaks down fats (lipids) into glycerol and fatty acids.

• Amylase

• Lipase

• Protease

• Cellulase

The specific region on an enzyme where the substrate binds.

• Active Site

• Binding Pocket

• Catalytic Center

• Enzyme Interface

The molecules produced from the enzyme-catalyzed reaction.

• Substrate

• Product

• Reactant

• Cofactor

The minimum energy required for a chemical reaction to occur.

• Activation Energy

• Catalytic Energy

• Thermal Energy

• Kinetic Energy

Cofactors and coenzymes are always unnecessary for enzyme activity.

• True

• False (Many enzymes require cofactors or coenzymes to function properly.)

• Only some enzymes require cofactors or coenzymes.

• Cofactors and coenzymes are only needed in extreme conditions.

The temporary molecule formed when a substrate binds to an enzyme.

• Enzyme-Substrate Complex

• Substrate-Product Complex

• Enzyme-Product Complex

• Active Site Complex

When an inhibitor binds to an allosteric site, changing enzyme shape and reducing function.

• Competitive Inhibition

• Non-Competitive Inhibition

• Irreversible Inhibition

• Feedback Inhibition

Enzyme inhibitors can slow down or stop enzymatic reactions.

• True (Inhibitors can bind to enzymes and reduce their activity.)

• False (Inhibitors have no effect on enzyme activity.)

• True (Inhibitors increase the rate of enzymatic reactions.)

• False (Inhibitors only affect non-enzymatic reactions.)

The protein portion of an enzyme, without its cofactor.

• Apoenzyme

• Holoenzyme

• Cofactor

• Substrate
