Enzymes

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms by lowering the activation energy required for the reaction.

Front

How do enzymes speed up reactions?

Back

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

Front

What is the pH range of a base?

Back

A base is a substance with a pH greater than 7.

Front

What is the pH of neutral substances?

Back

Neutral substances have a pH of 7.

Front

What happens to enzymes at high temperatures?

Back

When enzymes are heated to high temperatures, their shapes are altered, a process known as denaturation.

Front

What are enzymes made of?

Back

Enzymes are primarily made of proteins.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where the three-dimensional structure of an enzyme is altered, affecting its function.

Front

What is the role of activation energy in chemical reactions?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

What is a substrate in enzyme activity?

Back

A substrate is the specific reactant that an enzyme acts upon.

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.
