Question

2 of 3 concepts completed multiple select question select all that apply observe the diagram. how does the diagram explain how enzymes affect the activation energy of a biochemical reaction. enzymes bring reactants together. without enzymes, reactants spend time randomly colliding with other molecules. enzymes change shape once reactants bind. this facilitates the breaking and forming of chemical bonds. enzymes add energy to a reaction, which lowers the amount of energy reactants need to form new bonds. enzymes add active sites to reactants. the active sites on reactants causes the reactants to combine more quickly.

Explanation:

Enzymes are biological catalysts. They bring substrates (reactants) together by binding them at their active - sites, reducing the random collision time of reactants. Also, when reactants bind to the enzyme, the enzyme changes shape which helps in bond - breaking and bond - forming processes. Enzymes do not add energy to a reaction; instead, they lower the activation energy. And they do not add active sites to reactants.

Answer:

Enzymes bring reactants together. Without enzymes, reactants spend time randomly colliding with other molecules.
Enzymes change shape once reactants bind. This facilitates the breaking and forming of chemical bonds.
