What would happen to this reaction if an enzyme was added? mark all that apply.

1) the reaction would progress faster.
2) the activation energy would be lowered.
3) the reaction would progress slower.
4) the activation energy would be increased.
5) there would be more products produced.
6) less reactions would be needed.

The reaction would progress faster and the activation energy would be lowered when the enzyme gets added.

Enzymes are proteins that basically speed up the chemical reaction without being used. Enzymes are usually specific for a particular substrate. The substrate in the reaction bind to the active site of the enzyme which is present on the surface of the enzymes forming the enzyme-substrate complex.

Performing the enzyme-substrate complex the enzyme changes the shape slightly so that the substrate can fit tightly to its active site. Then this enzyme-substrate Complex undergoes a reaction to form a product. Enzymes lower the activation energy of a reaction i.e the required amount of energy needed for a reaction to occur.They do this by binding to a substrate and holding it in a way that allows the reaction to happen more efficiently.
