Explanation:
Models can be conceptual, graphical or mathematical as they are used in science. It allows one to break down a concept into simpler terms with a visual component. A limitation of models in science is that they are usually simplified versions of the real situation or concept.
<span>When an atom gains or loses an electron it's called an ion. Ions have a net positive or negative electrical charge. If an atom loses electrons, it has a net positive charge . If an atom gains electrons, it has a net negative charge and is known as an anion..</span>
The right answer is A) lower the activation energy of chemical reactions.
The enzyme accelerates the reaction without changing the steady state.
Enzymes lower the activation energy of the substrate.
Activation energy or free activation energy is the energy that must be absorbed by the reagents to break their bonds.
The reagents must reach an unstable transition state in which the bonds are more fragile and easier to break.
Even an exergonic reaction requires the absorption of energy to reach the transition state.
