Concept 1 Review

Front

What is the role of an enzyme in a chemical reaction?

Back

Enzymes speed up reactions by lowering the activation energy required for the reaction to occur.

Front

What is the active site of an enzyme?

Back

The active site is the specific region on an enzyme where the substrate binds and the reaction takes place.

Front

Define substrate in the context of enzymatic reactions.

Back

A substrate is the reactant molecule that an enzyme acts upon during a chemical reaction.

Front

What happens to a substrate after it binds to an enzyme?

Back

After binding, the substrate undergoes a chemical reaction and is transformed into products.

Front

What is the difference between endothermic and exothermic reactions?

Back

Endothermic reactions absorb energy, while exothermic reactions release energy.

Front

Give an example of an exothermic reaction.

Back

Combustion of fuels, such as burning wood or gasoline, is an example of an exothermic reaction.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

How do enzymes affect activation energy?

Back

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

Front

What are products in a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to select and catalyze only one specific substrate or a group of closely related substrates.
