Question

1. what type of reaction is shown in the graph? how do you know? 5. how does an enzyme work? 6. what does it mean to be denatured? what are 2 ways it can happen? 7. complete the following table:

Explanation:

4.

The graph shows that the energy of the reactants is higher than that of the products, with energy given out to the surroundings. In an exothermic reaction, heat is released to the surroundings, which is consistent with the graph.

Enzymes are biological catalysts. They work by binding to specific substrates at their active - sites. This lowers the activation energy required for the chemical reaction to occur, thus increasing the reaction rate.

Denaturation means the loss of a protein's (including enzymes) native three - dimensional structure. It can occur due to high temperatures, which disrupt the weak bonds (such as hydrogen bonds) maintaining the protein's shape, and extreme pH levels that can also disrupt these bonds.

Answer:

It is an exothermic reaction. We know this because the energy of the reactants is higher than the energy of the products and energy is given out to the surroundings.
