ET Enzymes Review 12/16/24

Front

What happens when enzymes are heated to a high temperature?

Back

The shapes of the enzyme are altered (denature).

Front

How does an enzyme's shape relate to its function?

Back

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

Front

What is the optimum temperature for enzymes?

Back

The optimum temperature for this enzyme is 52 degrees Celsius.

Front

How are enzymes in bacteria affected at temperatures lower than their optimal temperature?

Back

The enzymes will not increase the rate of reactions as much as they would at their optimal temperature.

Front

What happens to pepsin as it enters the small intestine from the stomach?

Back

It becomes inactive.

Front

Define denaturation in the context of enzymes.

Back

Denaturation is the process where the enzyme's structure is altered, affecting its function.

Front

What is the role of pH in enzyme activity?

Back

Different enzymes have optimal pH levels at which they function best; extreme pH levels can denature enzymes.

Front

What is a substrate in enzymatic reactions?

Back

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

Front

Explain the term 'active site' in enzymes.

Back

The active site is the region on the enzyme where the substrate binds and the reaction occurs.

Front

What is the effect of temperature on enzyme activity?

Back

Increasing temperature generally increases enzyme activity up to a certain point (optimum temperature), after which activity decreases due to denaturation.
