Describe the effect of an enzyme on the activation energy in a chemical reaction.

Enzymes are biological catalyst meaning they speed up reactions. They do this by lowering the activation energy which results in bond breaking much faster, leading to a quicker chemical reaction.

In conclusion, enzymes speed up a chemical reaction by lowering the activation energy, resulting in a faster rate of reaction as bonds break quicker.

Hope this helps even though its quite simplified! :)

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
