Enzymes (SB1c)

Front

What color line represents a reaction with an enzyme present?

Back

Blue

Front

What mechanism describes how each substrate must fit into the enzyme?

Back

Lock and key

Front

What are enzymes?

Back

Proteins that speed up chemical reactions by lowering the amount of activation energy required to start the reaction.

Front

Why are enzymes necessary for reactions in our cells?

Back

The reactions are too slow to meet the needs of the cell if enzymes are missing.

Front

What happens to an enzyme when there are changes in pH and temperature?

Back

It can denature, causing it to lose its shape and affecting its function.

Front

What is the role of activation energy in chemical reactions?

Back

It is the energy required to start a chemical reaction.

Front

What is denaturation in the context of enzymes?

Back

The process where an enzyme loses its shape and functionality due to external factors like temperature and pH.

Front

What is the primary structure of an enzyme?

Back

The sequence of amino acids that make up the enzyme.

Front

What is the active site of an enzyme?

Back

The region on the enzyme where the substrate binds.

Front

How do temperature changes affect enzyme activity?

Back

Increased temperature can increase activity up to a point, after which the enzyme may denature.
