In the Lock-and-Key model of enzyme function, Step 3 typically involves the binding of the substrates to the enzyme's active site, leading to the formation of an enzyme-substrate complex. In this context, if we consider that Step 3 refers to the reaction process following substrate binding, the most appropriate answer would be:
**Chemical bonds are weakened and are breaking down.**
This indicates that the enzyme is facilitating the conversion of substrates into products by destabilizing their bonds, allowing for the chemical reaction to occur.
If the answer options pertain directly to the steps of the reaction without specifying that binding is already taking place, another option may be more fitting depending on the specific sequence being described in the diagram. However, based on common interpretations, the weakening of chemical bonds aligns well with enzymatic function at this stage.
