Enzymes

Front

What is a substance called if it speeds up a chemical reaction?

Back

Catalyst

Front

What is the optimum pH of the enzyme if the graph indicates a peak at 6.6?

Back

The optimum pH of the enzyme is 6.6.

Front

Enzymes speed up reaction rates by changing what?

Back

Activation Energy

Front

Which enzyme is most efficient in an acidic solution?

Back

Enzyme A

Front

What is the function of an enzyme?

Back

Enzymes speed up chemical reactions.

Front

What is the role of a catalyst in a chemical reaction?

Back

A catalyst lowers the activation energy required for a reaction to occur.

Front

How do enzymes affect the activation energy of a reaction?

Back

Enzymes lower the activation energy, making it easier for the reaction to occur.

Front

What happens to enzyme activity as pH increases from 5.0 to 9.0?

Back

The enzyme’s activity increases until it reaches its optimum pH.

Front

What is the effect of temperature on enzyme activity?

Back

Enzyme activity typically increases with temperature up to a certain point, after which it may denature.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to extreme conditions.
