Enzymes

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms without being consumed in the process.

Front

What is activation energy?

Back

Activation energy is the minimum amount of energy required to initiate a chemical reaction.

Front

How do enzymes affect activation energy?

Back

Enzymes decrease the activation energy required for a reaction, allowing it to proceed more quickly.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without undergoing any permanent chemical change.

Front

What is the optimum pH for an enzyme?

Back

The optimum pH is the pH at which an enzyme's activity is at its maximum.

Front

What happens to enzyme activity at extreme pH levels?

Back

Extreme pH levels can denature enzymes, causing them to lose their shape and function.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme loses its three-dimensional structure, rendering it inactive.

Front

What is the role of substrates in enzyme reactions?

Back

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

Front

What is the enzyme-substrate complex?

Back

The enzyme-substrate complex is a temporary molecule formed when an enzyme binds to its substrate.

Front

Can enzymes be reused?

Back

Yes, enzymes can be reused multiple times in reactions as they are not consumed.
