How does an enzyme help a reaction to occur in the cell?

It gives the reaction more energy.

It increases the amount of energy needed.

It takes excess energy away from the reaction.

It lowers the energy needed for the reaction to occur.

Enzymes are biological catalysts – they speed up chemical reactions. Enzymes are required for most of the chemical reactions that occur in organisms . These reactions occur in the breakdown of chemical molecules, which we see in the digestive system . ... Enzymes are proteins that have a complex 3D-shape.
