Factors Affecting Enzyme Function

Enzymes facilitate complex reactions by binding to substrates at the active site, undergoing catalysis to transform substrates into products. Enzyme function is influenced by structure, temperature, pH, and concentration. High temperatures and pH changes can alter enzyme shape, affecting activity. Increasing substrate or enzyme concentration boosts reaction rates up to a point. Key factors affecting enzyme function include temperature, pH levels, and concentration.

What is the role of the active site in enzyme function?

• It is the location where substrates bind to the enzyme.

• It is where enzymes are synthesized.

• It is where enzymes are stored.

• It is the part of the enzyme that gets destroyed during reactions.

How does temperature affect enzyme activity?

• It makes enzymes more acidic.

• It can change the enzyme's shape, affecting its function.

• It only affects the enzyme's color.

• It has no effect on enzyme activity.

What happens to an enzyme if the pH level is significantly altered?

• The enzyme starts producing more substrates.

• The enzyme becomes larger.

• The enzyme's shape may change, making it unproductive.

• The enzyme becomes more active.

What is the effect of increasing substrate concentration on enzyme activity?

• It increases the rate of reaction indefinitely.

• It has no effect on the rate of reaction.

• It increases the rate of reaction up to a certain point.

• It decreases the rate of reaction.

How does increasing enzyme concentration affect the rate of reaction?

• It has no effect on the rate of reaction.

• It stops the reaction completely.

• It decreases the rate of reaction.

• It increases the rate of reaction up to a certain concentration.
