Answer:
Activation energy may be defined as the minimum amount of the energy required to convert the substrate into the product. The higher the activation energy of a reaction, the slower the speed of a reaction.
The enzymes decreases the activation energy of the reaction and increases the effective collision between the substrate. The enzymes does not change the DG (delta G) or free energy of the reaction. The enzymes maintain the equilibrium of the reaction by increasing the equal amount of the forward and backward rate of the reaction.
Answer:
When you change the order of the base pairs in an organism, that is called a mutation. There are three types of mutations: a deletion, an addition, and a substitution. In a deletion, one of the three bases in a codon is pulled out, or deleted.
