Macromolecules and enzymes

Front

What type of macromolecule are enzymes?

Back

Enzymes are proteins that act as catalysts in biochemical reactions.

Front

What is the optimal temperature for enzyme activity?

Back

The optimal temperature for enzyme activity is the temperature at which the enzyme functions best, often around 30°C for many enzymes.

Front

What term describes the specificity of enzymes for their substrates?

Back

The term is 'specificity', meaning each enzyme only binds to a specific substrate.

Front

How can an enzyme and substrate be compared?

Back

An enzyme and substrate can be compared to a 'lock and key', where the enzyme (lock) only fits a specific substrate (key).

Front

What does a substrate become after an enzyme catalyzes a reaction?

Back

After the reaction, the substrate becomes a product.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes speed up biochemical reactions by lowering the activation energy required.

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 happens to enzymes at high temperatures?

Back

At high temperatures, enzymes can denature, losing their shape and functionality.

Front

What is the effect of pH on enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can reduce activity or denature the enzyme.
