Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms by lowering the activation energy required for the reaction.

Front

How do enzymes increase the rate of a chemical reaction?

Back

Enzymes increase the rate of a chemical reaction by reducing the activation energy needed for the reaction to occur.

Front

What happens to enzymes at high temperatures?

Back

At high temperatures, enzymes can become denatured, meaning their shapes are altered, which affects their ability to function.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where the three-dimensional structure of an enzyme is altered, usually due to extreme temperature or pH changes, rendering it inactive.

Front

Can pH changes affect enzyme activity?

Back

Yes, changes in pH can alter the active site of an enzyme, affecting its ability to bind to substrates and catalyze reactions.

Front

What is the active site of an enzyme?

Back

The active site is the specific region of an enzyme where the substrate binds and the reaction occurs.

Front

What is a substrate in enzymatic reactions?

Back

A substrate is the reactant molecule that an enzyme acts upon during a chemical reaction.

Front

What do enzymes become after catalyzing a reaction?

Back

After catalyzing a reaction, enzymes remain unchanged and can be reused, while the substrate is converted into a product.

Front

What is an enzyme-substrate complex?

Back

An enzyme-substrate complex is the temporary structure formed when an enzyme binds to its substrate.

Front

What role do enzymes play in metabolism?

Back

Enzymes play a crucial role in metabolism by facilitating biochemical reactions necessary for life, including digestion and energy production.
