Enzymes

Front

What is an enzyme?

Back

An enzyme is a protein that acts as a catalyst to speed up chemical reactions in biological processes.

Front

How do enzymes speed up reactions?

Back

Enzymes speed up reactions by lowering the activation energy required for the reaction to occur.

Front

What is the optimal temperature for an enzyme?

Back

The optimal temperature is the temperature at which an enzyme functions most efficiently.

Front

What is the optimal pH for an enzyme?

Back

The optimal pH is the pH level at which an enzyme is most active.

Front

What happens to enzymes at extreme temperatures?

Back

Extreme temperatures can denature enzymes, altering their structure and function.

Front

What is the role of substrates in enzyme activity?

Back

Substrates are the reactants that enzymes act upon to facilitate a chemical reaction.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to choose exact substrates from a group of similar chemical molecules.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

Front

What is the active site of an enzyme?

Back

The active site is the region on the enzyme where the substrate binds and the reaction occurs.

Front

What is the effect of concentration on enzyme activity?

Back

Increasing substrate concentration generally increases enzyme activity until a saturation point is reached.
