Front

How do enzymes affect the activation energy of a reaction?

Back

They lower the activation energy.

Front

What is the optimal temperature for enzyme activity based on typical graphs?

Back

Enzymes often work best at specific temperatures, such as 30°C for some enzymes.

Front

What is the primary function of enzymes in biological reactions?

Back

Enzymes speed up chemical reactions.

Front

What is the effect of pH on enzyme activity?

Back

Enzymes have optimal pH levels; deviations can lead to denaturation.

Front

What is an enzyme-substrate complex?

Back

It is the temporary complex formed when an enzyme binds to its substrate.

Front

What role do cofactors play in enzyme activity?

Back

Cofactors assist enzymes in catalyzing reactions.

Front

What is the difference between competitive and non-competitive inhibition?

Back

Competitive inhibitors bind to the active site, while non-competitive inhibitors bind to another site.

Front

How does temperature affect enzyme activity?

Back

Increased temperature generally increases activity to a point, after which denaturation occurs.
