How does an enzyme influence a biological reaction?
Question 10 options:

It increases the net energy difference between reactants and products.

It decreases the activation energy necessary to initiate the chemical change.

It increases the kinetic energy of reactants, thereby increasing their tendency to collide.

It decreases the kinetic energy of reactants, enabling them to undergo chemical change more easily.

It decreases the activation energy necessary to initiate the chemical change.

Explanation:

Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

every el niño cycle is different. every year.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
