What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms without being consumed in the process.

Front

How does the shape of an enzyme relate to its function?

Back

The enzyme is shaped specially for certain substrates to perform a specific reaction.

Front

What happens to the pH of a solution when H+ ions are added?

Back

The pH would go down.

Front

What is the pH of a weak acid?

Back

A weak acid typically has a pH less than 7 but greater than 0.

Front

What is the pH of a strong acid?

Back

A strong acid typically has a pH close to 0.

Front

What is the pH of a strong base?

Back

A strong base typically has a pH close to 14.

What is the pH of a weak base?

Back

A weak base typically has a pH greater than 7 but less than 14.

Front

Why is the shape of an enzyme important?

Back

A specific substrate needs to fit perfectly into its activation site.

Front

What is a substrate in the context of enzymes?

Back

A substrate is the reactant molecule upon which an enzyme acts.

Front

What is the role of an active site in an enzyme?

Back

The active site is the region of the enzyme where substrate molecules bind and undergo a chemical reaction.
