What is the relationship between enzymes and activation energy?

Hello!

Chemical reactions require energy to begin. The reactants must collide with enough energy for bonds to change. This energy is known as activation energy - the difference in energy between that of the reactants and the amount needed for the reaction to occur.

Catalysts lower the activation energy needed for a chemical reaction to occur, therefore also increasing the rate of a reaction. Enzymes are proteins which act as catalysts within cells.

Therefore, enzymes cause the activation energy to lower.

Hope this helps!

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
