Enzymes

Front

What happens when enzymes are heated to a high temperature?

Back

The shape of the enzyme changes and it denatures.

Front

What is a competitive inhibitor?

Back

A substance that slows down a reaction by binding to the active site of an enzyme, preventing the substrate from binding.

Front

How do enzymes speed up reactions?

Back

By lowering the activation energy required for the reaction to occur.

Front

What does it mean for an enzyme to be specific?

Back

Each enzyme only has one substrate that will fit its active site.

Front

What is the active site of an enzyme?

Back

The region on the enzyme where the substrate binds.

Front

What is denaturation in the context of enzymes?

Back

The process where the enzyme's structure is altered, rendering it inactive.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, substrate concentration, and the presence of inhibitors.

Front

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

Back

To increase the rate of the reaction without being consumed in the process.

Front

What is the relationship between enzyme concentration and reaction rate?

Back

Increasing enzyme concentration generally increases the reaction rate, provided there is enough substrate.

Front

What is substrate specificity?

Back

The ability of an enzyme to choose exact substrate from a group of similar chemical molecules.
