How Enzymes Catalyze Reactions

Enzymes can change the final products of a reaction.

Enzymes increase the temperature of the reaction.

Enzymes lower the activation energy required for a reaction to occur.

Enzymes are consumed in the reaction process.

Active sites are only involved in the transport of substrates.

Active sites are the part of the enzyme that stores energy.

Active sites change the enzyme's overall shape permanently.

Active sites provide a specific region for substrate binding and catalysis.

Enzymes are specific to particular substrates due to their unique active site structures.

Enzymes can bind to any substrate regardless of the structure.

All enzymes have the same active site and can catalyze the same reactions.

Enzymes can only function in high temperatures and pH levels.

Enzymes are most active at their lowest temperatures.

Higher temperatures always lead to increased enzyme activity.

Temperature does not affect enzyme activity.

Increasing temperature generally increases enzyme activity up to an optimal point, beyond which activity declines.

pH does not influence enzyme activity or structure.

Each enzyme has an optimal pH at which it functions best; extreme pH levels can denature the enzyme and reduce activity.

All enzymes work best at a neutral pH of 7.

Enzymes function better in acidic conditions only.

Enzyme inhibitors increase the speed of enzyme-catalyzed reactions.

Enzyme inhibitors decrease or prevent enzyme activity, thereby regulating metabolic pathways.

Enzyme inhibitors change the substrate into different products.

Enzyme inhibitors have no effect on enzyme function.

Only substrate concentration affects the rate of enzyme reactions.

The rate of an enzyme-catalyzed reaction is solely dependent on temperature.

Substrate concentration, temperature, pH levels, and enzyme concentration can all affect the reaction rate.

Enzymes only work when the substrate concentration is low.

They act as substrates themselves in enzyme reactions.

Cofactors and coenzymes are inactive and do not influence enzyme reactions.

Cofactors and coenzymes assist enzymes in catalyzing reactions by enhancing their activity.

Cofactors and coenzymes prevent enzymes from functioning.

Denaturation is when enzymes bind more substrates.

Enzyme denaturation is the process where an enzyme loses its three-dimensional structure and, consequently, its activity due to changes in environmental conditions.

Denaturation makes enzymes work faster by increasing their stability.

Enzyme denaturation is the activation of an enzyme at high temperatures.

Km indicates the total amount of enzyme present in a reaction.

A lower Km value means the enzyme has lower affinity for its substrate.

Km represents the substrate concentration at which the reaction rate is half of the maximum velocity (Vmax).

Km is the rate at which enzymes are produced.
