D. atomic structure of

Answer 1

Chemical reactions are primarily used to alter the energy of the products relative to the reactants, often involving the release or absorption of energy for bodily functions or production purposes. Enzymes lower the activation energy of reactions, making them crucial for life's biochemical processes.

Step-by-step explanation:

The main reason we use chemical reactions is to alter the energy of the products vs the reactants. The goal of a chemical reaction is often to release or absorb energy. For instance, the macronutrients in our food undergo metabolic reactions which release energy necessary to keep our bodies functioning. Similarly, burning fuels like gasoline and natural gas provides energy for transportation and heating. Industrial chemical reactions can require significant amounts of energy to produce materials like iron and aluminum, which are then used to create other products.

In terms of the mechanics of reactions, enzymes play a vital role because they lower the activation energy of reactions, allowing them to proceed more quickly and at lower temperatures than would otherwise be possible. These enzymes are critical for maintaining the numerous biochemical reactions necessary for life.
