Catalyst is any substance that causes or increases the rate of a chemical reaction without itself being consumed For example - enzymes are biocatalysts.

The catalyst can speed up a chemical reaction by reducing the activation energy or by changing the reaction mechanism.

The minimum amount of extra energy required by a reacting molecule to get converted into the product is defined as activation energy.

So, the correct answer is The catalyst decreases the reaction energy needed.

Other options-

The catalyst increases the concentration of products- incorrect. Catalysts do not affect the equilibrium concentrations of products or reactants. The catalyst binds to enzymes to release substrates- incorrect. The catalyst binds to the substrate and converts the substrate into products.The catalyst increases the concentration of reactants- incorrect. Catalysts do not affect the equilibrium concentration of products or reactants.

Answer from: Oso29

The catalyst decreases the reaction energy needed.

Explanation:

The catalyst speeds up chemical reactions by decreasing the amount of activation energy/reaction energy needed in the reaction.

Compared to reactions without catalysts, they are much faster because there is less activation energy needed.

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
