Question

For each of the following sentences, fill in the blanks with the best word or phrase selected from the list below. Not all words or phrases will be used; each word or phrase should be used only once.

By definition, catalysis allows a reaction to occur more __________________. Chemical reactions occur only when there is a loss of __________________ energy. Enzymes act more __________________ than other catalysts. A catalyst decreases the __________________ energy of a reaction.

activation, free, selectively, chemical bond, kinetic, slowly, completely, rapidly, unfavorable, favorable

Answer 1

By definition, catalysis allows a reaction to occur more rapidly. Chemical reactions occur only when there is a loss of free energy. Enzymes act more selectively than other catalysts. A catalyst decreases the activation energy of a reaction. Catalysis enables reactions to proceed more rapidly, by reducing free energy requirements and activation energy, while enzymes increase selectivity and efficiency of these processes.

Step-by-step explanation:

By definition, catalysis allows a reaction to occur more rapidly.

Chemical reactions occur only when there is a loss of free energy.

Enzymes act more selectively than other catalysts.

A catalyst decreases the activation energy of a reaction.
