Enzymes

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

Do enzymes speed up reactions without using heat?

Back

False. Enzymes can speed up reactions without the need for heat.

Front

What do acids release?

Back

Acids release hydrogen ions (H+).

Front

What do bases release or pick up?

Back

Bases release hydroxide ions (OH-) or pick up hydrogen ions (H+).

Front

What are salts made of?

Back

Salts are made of cations (+) and anions (-).

Front

How do salts affect enzymes?

Back

Salts can interfere with and break bonds within the tertiary structure of proteins (enzymes), potentially affecting their function.

Front

What happens if an enzyme is inhibited or mutated?

Back

If an enzyme is inhibited or mutated, it may not be able to create certain intermediates necessary for a reaction.

Front

What is the role of an enzyme as a catalyst?

Back

The role of an enzyme as a catalyst is to lower the activation energy to increase the speed of reactions.

Front

What is the active site of an enzyme?

Back

The active site is the specific region on an enzyme where substrates bind and undergo a chemical reaction.

Front

What is the enzyme-substrate complex?

Back

The enzyme-substrate complex is formed when a substrate binds to the active site of an enzyme.
